If the father has color-blindness and the mothers family doesn't,?
Question:
Answers:
The chances are 0%.
Because a boy, doesn't inherit the X from his father, where color blindness is encoded. And a girl always receives a normal X from her mother, which is stronger than the colorblind X from her father. She will be a carrier to 100% but not colorblind herself.
This is true for red-green color blindness. Other forms have a different inheritance pattern.
50/50 but on your mom side. your father got it from his mom
A lot of men are color blind. I'm sure some women are to. However, it is dominant in men.
Colour blindness is X linkage chromosomes . So, if your father is CB person and your mother not (and without any family history) :
Your father ------ XY = Xcb + Y
Your mother ---- XX = X + X
(Xcb = X with colour blind)
So their kids will probably
1. XcbX = female normal, carrier.
2. XY = male non carrier, normal.
I can't speak for all the complicated genetics behind this question but I can say that my dad is red/green color blind, my mom is not. None of the children are color blind and, as far as I know, none of the grandchildren are color blind.
