What color is Nessie?

About halfway through the Deeprun Tram, at the bottom section of glass tubes, you can glimpse a large monster named "Nessy." This is a reference and nickname for the legendary Loch Ness monster, which the World of Warcraft monster resembles.

Because the Deeprun Tram is its own instanced zone (similar to a dungeon or battleground), you cannot find Nessy nor the environment outside the glass tunnel anywhere else in the game world. The glass is impassible without exploiting, so there is no way to interact with Nessy other than targeting it.

Some people say thay got to Nessy by charging through the glass (as a warrior) but that is still in question, and even if you do you will most likely get banned.

How can you see the aura color of someone?

You can find clubs to go too and they have the equipment to do it. You have to have a darkened room, you are standing in front of a dark back-drop, and they use an ultra violet light (sometimes a black light). It's amazing. No one has the same color of aura. When we get angry our aura goes red and splits up into small jagged specters such as the Northern lights and when we are happy or sad the aura changes again. I found it facinating. If you look at paintings of Jesus you will see he has only an aura around his head (no one has that) us humans have complete auras around our bodies. Yours pets, plant life and every living thing has an aura. You can also go into any specialty book store that carries crystals, stones, etc., and ask them where you could find someone that can read auras. This is nothing new and as I said before it's being used in medical science to help find health issues in patients quicker than tests. In the future I have no doubt that this will be the way the medical profession will go (and it costs less for the medical insurance and the patient.) Please go onto: www.google.com TYPE IN: All about auras You will see an actual diagram where they have cut a wide leaf in half, but when you put it under the right conditions you can actually see the green part of the leaf, then the energy of the aura of the rest of the leaf. Technically, the leaf is still in one piece! Marcy

Are bovine color blind?

Cows are not colour blind. They are dichromatic, in other words they can only see in yellows and blues.

Why are there more colorblind males than there are colorblind females?

Colorblindness is a trait that is linked to our X chromosome - it's a sex-linked, recessive trait that is attached to the X chromosome.
For males, the 23rd pair is XY, and for females, XX.

The trait for colorblindness lies on the X chromosome and can either be dominant or recessive. (For my example, we'll just say X' for recessive and X dominant for simplicity's sake.)

Females have the advantage of having two X chromosomes. I won't go in to specific detail, but the possible combinations of chromosomes for females would be XX, X'X, XX', and X'X'. Only with X'X', would a female be colorblind.

As for males, they only have one X chromosome, and the combinations are XY or X'Y.

As you can see, the chances of colorblind males are much, much higher due to having only one X-chromosome, which is why you'll find more colorblind males than colorblind females.
Of course, there is much more to it than just that, but that goes way beyond the scope of what I can remember. And I'm not too much in the mood of reopening my genetics textbook. ;)

Who is more apt to color blindness - males or females?

Genetic red-green color blindness affects men much more often than women, because the genes for the red and green color receptors are located on the X chromosome, of which men have only one and women have two. Such a trait is called sex linked Females (46, XX) are red-green color blind only if both their X chromosomes are defective with a similar deficiency, whereas males (46, XY) are color blind if their single X chromosome is defective. This sentence means that if both of the X chromosomes women are reccesive ten she has a color blindness trait. If the X chromosomes has one dominant X and one reccesive trait then she doesn't have the color blindness trait. The people who have color blindness trait are called a carrier.

What kind of non-mendelian trait is color blindness?

Its a Sex-Linked Trait, so for girls it would be XCxC or XCXcfor it recessivly for boy (They have the greater chance of getting the trait because its only located on the X chromosome) so for boys its XCY for the trait and XcY for it recessivly

Why is colour blindness more common in males?

The genes that produce photopigments are carried on the X chromosome; if some of these genes are missing or damaged, color blindness will be expressed in males with a higher probability than in females because males only have one X chromosome (in females, a good gene on only one of the two X chromosomes is enough to yield the needed photopigments).

Is white a color or the absense of color?

In additive synthesis (light), White is a combination of all colors (Red, Green, an Blue)... In subtractive synthesis (pigment), White is the absence of all color.

Of course, white is not really a color at all, but is used as a color reference.

A person can technically argue that black and white are the same, because neither one is a color of itself, and both are the combination of all colors, but don't expect anyone to believe it (they are exact opposites).

Are albino people color blind?

They have an inability to absorb pigment anywhere in their bodies, this would include their eyes. In our eyes, the fovea is the main source of 'sight' since it allows us to se details and color. An albino's fovea is usually underdeveloped, hence making them anywhere between mildly colorblind, to completely blind.

How do you have a colorblind son if neither parent is colorblind?

It is just the DNA lottery. If neither parent is colorblind that just means that one of them (or both of them) have recessive genes for colorblindness that happened to show up in this particular child.

Are color blindness and blindness the same thing?

No - colour-blindness is the inability of the brain to interpret correctly colours that the eyes see, or maybe the eyes have a defect in their structure that sends the wrong signals to the brain. Blindness (total?) is when the eyes are unable to send visual signals to the brain at all. Maybe the optic nerve is damaged, or the eyes themselves are damaged - there are various medical reasons for the cause of blindness.
