Hello students, in this question we have been asked about hemophilia.
00:06
So, hemophilia is a sex -linked recessive condition.
00:18
So, a man with hemophilia marries a woman who does not have hemophilia or any family history with respect to that trait.
00:31
So, that portion of the sentence represents that women, the woman here is not a carrier.
00:42
So, this is the genotype.
00:47
So, let us do the cross here.
00:51
So, xh, y, xh, xh.
00:57
So, here we will have a girl that is a carrier and then again another girl who is a carrier.
01:08
Then we have a boy that is normal and another boy who is also normal.
01:20
So, nobody in this couple, no offsprings will have hemophilia.
01:31
But the female will be carriers and the male will be normal.
01:41
So, based on this, all daughters of this couple will have heterozygous for hemophilia...
