So the gene for colour blindness is a recessive sex link trait.
00:08
So this is colour blindness and this gene is a recessive, which means that unless it's expressed on both x chromosomes, we can say that this person is a colourblind, okay? but this uh incident here is a colorblind female right this is a colorblind male these are colorblind male colorblind female but this is a normal female okay okay and this is also a normal male okay so we look for these traits when we're doing this close among these individuals okay so now we are told in this question that a normal woman, that a normal woman, a normal woman, okay, or female, that will be x.
01:22
That, okay, so this is a normal female, marries a colorblind male, and colorblind male, in this case, will now be, well, having that gene for colorblindness in the l.
01:39
And the x chromosome, which means that the gametes for these are cross.
01:48
The gametes here will be xb and x for the female, and we are crossing that with the male, and the male as a colorbliness, so these are the gametes...
