if a color blind woman marries a normal vision man and they have ten children how many will have normal vision

Answer 1

probably none, but its depends on which parents genes are more dominant

Answer 2

Only 0.4% of women have some form of color blindness, so the chances of the woman being colorblind is VERY rare. But, lets say she is, if they have daughters in those 10 children, chances are none of them will be colorblind. Color blindness is not contagious in any way. People will become color blind because they have received the color blind gene from the X chromosome of their mother when they were born. The condition usually presents by the age of twenty and most patients will lose vision from the 20/200 level by the age of 30. Color blindness is usually hereditary and is inherited through a dominant gene. So it is basically the luck of the draw. There is no certain way to tell how many will or will not be colorblind.

Answer 3

Only men can be color blind- but women can carry the it as a recessive gene. You can't tell unless you ran tests on the male to see if he has the gene as a recessive trait as well.
if he did then ..... 2 of every 4 children would carry it as a recessive trait the other 2 would be clear

if he does carry the gene then .... out of 4 children 2 would carry it as a recessive trait & 1 would be color blind.

Now i'm not saying that if he had 4 kids thats for sure how it would turn out. but for every child these are his chances. does that make sence?
So its more like he has a 50% chance that a child would carry the recessive trait. and if he did have the recessive gene then there is a 50% chance of his child carrying the recessive trait of colorblindness and a 25% chance of a child being colorblind... if its a boy? hehe

Answer 4

All daughters will have normal vision, as they will have x-chromosomes from the father which carry the good genes. But they will be recessive carriers of the trait, and the daughters' sons may be colorblind (50% chance). All sons will be colorblind, as the only x-chromosome they inherit will be the defective one from mom..
Postscript, for vlalto: Women can be colorblind, and I have a lady friend who is. If Daddy is colorblind, and Mommy is a carrier, daughter will have a 50% chance of being colorblind.

Answer 5

The colour blind gene comes from the X chromosome (mother's side) and it is usually passed to males. So it depends on the sex of the children, males being more likely than females. So I would say 50-50 chance. Which means, some might and some might not.

Answer 6

All of the girls will be normal, all of the boys will be colourblind.

Let Xc = colourblind gene X= normal X chromosome and Y = Y chromosome

To have normal vision a person needs ONE good X chromosome

Mother is Xc Xc, Father is X Y
All girls are Xc X (Carriers - they have normal vision but can pass on the gene to their children.)
All boys are Xc Y (colourblind)

Answer 7

Being colorblind is not extremely common. It is more likely that the majority, if not all children will have normal vision.

Answer 8

Been a while since I've taken a bio class, but if I remember correctly, isn't color blindness carried on the male chromosome? So I'm not sure how the wife got her affliction, but he kids should all be okay.

Answer 9

Most of all the boys will be color blind. The girl children will just be carriers of color blindness.

Answer 10

anticipate X is the conventional gene and x is the colour-blind gene. mom: Xx Father: xY little ones: Xx, xx, XY, xY there's a 50% threat that the youngsters would be shade-blind, a 25% threat that a son with widespread innovative and prescient is born, and a 25% threat that a daughter with widespread innovative and prescient yet service of shade-blindness is born.

Answer 11

2.5 on the average if the woman is a man
