Color Blindness

Everyone can be affected by monochromatic color blindness. Monochromatic color blindness is a condition where your color blind in only one eye.

For example, if a mother is a carrier for colorblindness (X+Xc), and a father has normal vision X+Y, then their sons have a 50% chance of colorblindness because they inherit their X chromosome from their mother and their Y chromosome from their father.

Color blindness is an X-linked trait. That means it is carried in the X chromosome, which differentiates whether a baby will be a girl or a boy. Women have two X chromosomes (XX), and men have an XY combination. If a woman is a carrier for color blindness, only one of her chromosomes will be affected (we'll call it a little "x"), and for that reason she will not be colorblind. Men, on the other hand, only have one X chromosome, so any time they carry the colorblindness gene, they will be colorblind.

A child inherits one chromosome from each parent. He/She will get an X chromosome from his/her mother, and an X from her father (if a girl) or a Y from his father (if a boy).

So, If a woman is a carrier, Xx, and a man is normal, XY, they have several different chances for different offspring:

XX (a normal girl)

XY (a normal boy)

Xx (a normal girl who carries the colorblindness gene)

xY (a colorblind boy)

The short answer is, that if a woman has a boy, he has a 50% chance of being colorblind.

. You could also get this disease when you are born

No they will produce a child who is colour blind.

You would have problems looking at traffic lights. Cooking food because you would not be able to tell if their meat is raw or well done. Color observations you would not be able to look at colorful flowers or things to that nature

We know that if a father is colorblind and the mother is neither colorblind nor a carrier, then the sons will not be colorblind. So, using logic, that means that the father can't cause a son to become colorblind. Process of elimination would point towards whenever a son is colorblind that it comes from the mother.

Well i speak from knowing somebody with this issue... they usually have trouble distinguishing all sorts of colors as well as brightness. This is a rather hard to explain question due to the fact there are so many different cases of color blindness... but i would have to say Red, Green, Blue, And yellow.

do a test

Cool colors would include: green, blue, and violet. Warm colors would include red, orange, and yellow.

The father has to be colorblind for the daughter to be colorblind because both X chromosomes must have the colorblindness gene in females because the colorblind gene is recessive. If only the mother is color deficient, then she merely passes on the gene to one of the X chromosomes in a female. If both the mother and father are both colorblind, then both X chromosomes in the female are effected and the female is colorblind.

There are two scenarios in which a daughter may be born colorblind.

1. The father is colorblind and the mother is a carrier of the colorblind gene. The daughter will be either colorblind or a carrier of the colorblind gene.

2. The father and mother are both colorblind. If this is the case, then all of the children will be born colorblind.

i searched a picture and it was brown. it could be other colors too tho. ...not sure....

About 8 percent of males, but only 0.5 percent of females, are color blind in some way or another, whether it is one color, a color combination, or another mutation. This is due to males only having one X chromosone - But that's another story.

Men are not just 'likely' to be colour blind, they are the 'only ones' who can suffer from colour blindness. This is because colour blindness is cused by an x-linked recessive gene, that is it can occur only if a person carries 2 of these x-linked recessive traits.

Now, females have one X and one Y chromosome,so in no way, they can have 2 X chromosomes.(exception-Klinefelter's syndrome, where thery is XXY trisomy)

Only men can have 2 X-chromosomes. Hence, females can only carry the colour blindness gene, while men can 'suffer' from colour blindness.

It could be inherited by the parents, that would be very likely, If the parents don't have color blindness, its not very likely.

people with color blindness is the main source of the doctors wide range of scores but they still to find the right ansers

There is no official count of how many people in the world are blind, nor is there one single definition worldwide of what constitutes blindness in a legal or formal sense. It is estimated that about 40 million people suffer from blindness worldwide, according to the standards used by the World Health Organization. Another approximately 245 million are considered visually impaired by this standard, but this number would include some considered blind under the legal standards of various nations.

One cannot describe colour to a blind person, no matter what the colour. Just as trying to describe a musical note to a deaf person would be impossible. -- To understand the description of a sensory experience one must have a pont of reference against which to compare it. A particular colour might be explicable to a partially-sighted person, or a musical not to a slightly-deaf person, but if the sense it totally lacking in them then they won't understand.

yes everyone have...so me myself i had also just being a little shy to talk to people but i tried to overcome it by interacting with them

No, it is genetic, and whatever degree of color blindness a person has at birth, they will go to their grave with.

It isn't only boys that are colorblind. It is just that it is much much more likely. In people, the genes that cause color blindness are on the same chromosomes that determine if you are physically a boy or a girl. So color blindness is usually called a "sex-linked" trait. If you are a boy you only need one copy of the gene to be color blind, from your mom. If you are a girl you need two copies, from both your mom and dad. Since it is harder to get two copies than one, there are a lot more color blind boys.

yes. but they can see colour when they run. the faster they run, the more blood flow stimulates their eyes and the more vibrant the colours become.
