I do not think that Semitic is a color, but a major branch of the Afro-Asiatic language family.
About a 74% estimated probability of green,
the colorblindness is usually not activited in a female body but is usually seen in male
Assuming that the man who has normal vision is homozygous for normal vision, the couple's daughter will either be homozygous for normal vision or heterozygous (normal vision but carrier for color blindness) for normal vision. In light of this, the couple's daughter will not be color blind.
Red green color blindness and hemophilia are two human genetic disorders that are caused by?
Red-green color blindness is caused by a mutation in the genes that code for red and green cone cells in the eyes, affecting color vision. Hemophilia is caused by mutations in genes that code for proteins involved in the blood clotting process, leading to difficulty in clotting. Both disorders are inherited in an X-linked recessive pattern.
Why is the color red an appetizing color for people?
It is appealing
Red is an appealing colour. It is eyecatching, and possibly makes you think of apples. Does some muddy brown colour make you want to eat? No, probably not. Red is much nicer, and generally not associated with something gross.
Try it out!
Have you tried eating blue colored rice? I did, and my appetite just vanished completely. I couldn't! Same with a blue cake. I baked it for class, but no one ate it. When you try this, make red and yellow colored rice too.
What side is blind in homonymous hemianopsia the cva side or the hemiplegic side?
Because of the way things are "wired" from the eye to the brain the hemiplegic side of each visual field is blind. For example if you have a stroke on the right side of your brain that causes a left sided hemiplegia (and also presumably affects the area of the brain responsible for sight) then you would not be able to see anything to the left of whatever you are fixating on in BOTH eyes.
...
This is because the right-sided stroke destroys nerve fibres that run through the right side of the brain from the right-side of each retina.
The result of losing these fibres is effectively the same as losing your right retina in both eyes --- this always results in a LEFT-sided visual field loss (left homonymous hemianopia) because the Right retinal wall of each eye sees the Left of the world because all light and images come to it through a small gap at the front of the eye (the pupil)
(ie - the right side of your retina can't see straight ahead of itself because the sclera is opaque and blocks all light - the only light that gets to the right of the retina is through the hollow pupil on its left - it can therefore only see the left of the world)
This can be seen clearly on a visual pathway diagram (google images)
Pitfall 1 - Remember that the term "homonymous hemianopia" refers to the symptom of vision loss and not the location of where the damage occurred (eg - a L-sided homonymous hemianopia is literally LOSS OF LEFT FIELD OF VISION)
Pitfall 2 - "the homonymous hemianopia should be R-sided if the Right brain is affected" This is wrong - failure of transmission of information from the Right retina occurs but this results in a Left-sided homonymous hemianopia (as per explanation above)
Pitfall 3 - "classic stroke won't affect vision as the occipital coretx isn't affected" - this is wrong - an infarct almost anywhere along the length of a cerebral hemisphere or even the internal capsule may disrupt visual nerve fibres, as they take a long course
In summary, Right-sided stroke = Left-sided hemiparesis/plegia and Left-sided homonymous hemianopia
THE HOMONYMOUS HEMIANOPIA IS ALWAYS ON THE SAME SIDE AS THE PARESIS

Is the color blindness gene also present on the Y chromosome?
No - the colour blindness gene is only found on the X chromosome.
Όμηρος [Homer] the ancient greek poet who wrote the well known epic poems of Iliad and Odyssey was blind.
No. If he was, in Ocarina of Time, he would not be able to tell the difference between the Zora, Goron and Kokiri tunics.
In physics it's the frequency of the light. That's O.K. for cameras and TV's.
In reality, it's a brain function - somewhere in the ocipitral lobe (toward the back of your head ---
because you see color with "too few" color discriminating cells to fit any of the cute color wheel therories.
Land (the poloroid guy) did some interesting work 40 years ago with two color film.
As above, color is your brain's interpretation of the frequency of light. A single color is created by one frequency of light (monochromatic). White light contains all of the frequencies of visible light from infra-red (long wavelength) through ultra-violet (short wavelength). If you look at a rainbow, you see white light separated into all of the colors that make it up. This is because, when light passes through a prism, it bends, but each separate frequency will bend to a different degree. So when you see a rainbow each band of color is caused by one frequency (actually a narrow range of frequencies) of light. With light different colors may be created by combining two or more monochromatic (individual frequencies) colors. The colors in the monitor you're viewing this with are created with only Red, Green and Blue light. This is called additive coloring. Most of the colors you see, though, are created by reflected light. Red paint looks red because it absorbs all of the colors in white light except red. Since the red light is not absorbed, it is reflected to your eye and your brain interprets the color as red. Unlike when mixing light, when you mix paints, you are combing materials that absorb different wavelengths of light to create colors. This is subtractive coloring. That is why the primary colors in light (red, blue and green) are different from those in paint (red, blue and yellow).
What are the intermediate colors?
Tertiary Colors
The intermediate colors are the "two-name colors" yellow orange, red orange, yellow green, blue green, red violet, and blue violet. They are created by mixing the primaries in specific proportions according to their proximity to a primary color of red, yellow, and blue on the color wheel. For example, if an orange is closest to yellow on the color wheel it means that it has more yellow in it and therefore looks like a yellowish orange. The orange that is next to the red on the color wheel has more red in it and therefore appears to look reddish.
Sometimes the intermediates are referred to as tertiary colors. The tertiary colors are not the same as intermediates as they are created by mixing the secondary colors. For example, orange and purple make russet, orange and green make citron, and purple and green make olive.
So really the intermediate colors are yellow orange, red orange, yellow green, blue green, red violet, and blue violet.
The igneous rock peridotite has a very high color index. It is comprised of more than 95% mafic minerals (like olivine), giving it a dark green color.
How do you describe the color gray to a blind person?
In order to describe the color gray to a blind person, it would be beneficial to connect it with one of the other senses. It may described as: the sound of footsteps on concrete, the smell of rain, the smooth texture of stainless steel.

This is dependent on which viewpoint one looks at this from. From a human viewpoint, crickets are indeed colorblind in that they cannot see certain colors that humans can see. However they can also see violet and ultraviolet wavelengths which humans cannot see. Crickets can see color, but not the color humans can see.
Is there a difference in billiard chalk due to its color?
color doesn't matter. it's just colored to match different felt colors. brands make the difference
What causes colors in smoke from the Red arrows?
The basic vapour colour is white, produced by injecting diesel into the hot exhaust from the jet engine. This reaches temperatures of over 400 degrees centigrade and vaporises immediately. The blue and red colours are made by mixing dye with the diesel. The dye and diesel is stored in a specially-modified pod fitted to each of the aircraft. The pilot releases the liquid by pushing one of three buttons on the control column. During the display each aircraft can produce smoke for a maximum duration of seven minutes. This gives the pilot five minutes of white smoke, and one minute each of red and blue smoke. For this reason, a 'smoke plot' is worked out extremely carefully to ensure that no aircraft runs out of smoke before the end of the display. Replenishing the diesel/dye mixture is done in two separate operations. First, the pressure which has built up in the centreline pod is released. Then, diesel is fed into the correct valve at the front of the centreline pod from a diesel bowser. There are no indicators to show when the diesel section of the pod is full - a technician is stationed at the rear of the pod to watch carefully for white vapour emitting from the vent pipe. Once the vapour is seen, the call of "It's Gone" is given and the technician in charge of the feeder pipe connected to the front of the pod turns the diesel supply off and shouts "White's Off". Replenishing the coloured dye/diesel mix is supervised particularly carefully to ensure the right colour mix is fed into the correct section of the pod. The most crucial piece of equipment for the team's work is the Dye Rig, which contains the dye/diesel mixture. Every display uses one barrel of red dye and one of blue dye, which are then topped up with diesel. The Team always fill the two colours in the same order to prevent confusion; red then blue. One technician operates the flow buttons on the dye rig, one connects the pipe to the valve at the front of the pod and one checks for the level at the rear of the pod. The call goes out "Red On", followed by "Pumping Red", at which point the Dye Rig operator presses the button to start the replenishment process. Again, there is no dial or gauge to show when the pod is full, and so the technicians have developed their own method of ensuring that the coloured liquid does not overflow. The only way to tell how full the pod is to press your ear up against the back of the pod to hear when the valve begins to quietly 'chatter' - quite difficult on a noisy airfield! Again, the urgent call of "It's gone" is followed by "Red Off" from both the Dye Rig operator and the pipe connector. The whole process is then repeated for the blue mixture. As you can imagine, the job of replenishing the dye and diesel can be a messy one! The dye is not easily removed if it stains skin and clothing. In order to protect the technicians against spillage, the Dye Team wear special protective silver overalls, thick gloves and goggles. Because of their protective qualities, the suits get extremely warm! Next time you watch the team replenishing diesel and dye on a hot summer's day, spare a thought for the hardworking Dye Team.
