So here in this question we'll be talking about colorblindness, which is an x -linked recessive disorder, which means that for a female to be a color blind, she must carry both the affected x chromosomes, but for a male, one affected x chromosome is enough.
00:26
Now here, we are taking xc as affected x chromosome and x as normal x chromosome.
00:41
Now in first part of our question, there's a cross between a colorblind male with a female who has normal vision.
01:03
Now if male is colorblind, which means he is carrying one affected x chromosome and the woman has both the normal x chromosomes here.
01:14
Remember that if woman is carrying one affected x chromosome, she will be normal but a carrier.
01:23
Now we are taking gametes of male on one side and gametes of female on another side the genotype of the offspring will be getting is a carrier female, normal male, again a carrier female and a normal male.
01:48
Here all offspring are non -colorblind.
02:05
Females are carriers...
