So here in this question, we are assuming that we are talking about pattern baldness.
00:06
So pattern baldness is an x -linked recessive disorder.
00:13
It's an x -linked recessive disorder, which means that for a female to be affected, she must carry both the affected x chromosomes.
00:22
Here, we are using x -b as the affected x -chromosome or the x -chromosome, which is carrying the recessively, and x -chromosome as the affected x -chromosomes.
00:33
The normal x chromosome or the x chromosome which is carrying the dominantly.
00:39
Over here, mother is not bald which means mother can be either homozygous x chromosome or is a carrier for petal barnes which means she is carrying one affected and one normal x chromosome and father is carrying normal x chromosome along with y chromosome.
01:07
Now there can be two situations.
01:10
First, when the mother is carrying both the normal x chromosomes and crossed with father...
