Answer 1

131.
This is called an INDEPENDENT ASSORTMENT.
The genes are separated from one another and sorted into
different gametes.
Option C is the answer.

151.
The 22 pairs of chromosomes which do not code for gender are
called as AUTOSOMAL chromosomes.
Option C is the answer

161.
XY= Male
XX= Female.
Option B is the answer

171.
The male donates X or Y, so determines the sex.
Option A is the answer.

181.
If a female is a carrier for hemophilia (XXh), her phenotype will be normal blood clotting
Option B is the answer

191.
The genotype of a male having hemophilia is XhY, this means the X chromosome
has come from MOTHER.
Option B is the answer.

201.
A female to be hemophilic, she must have both recessive genotypes.
Her genotype is XhXh which means she got her genes both from
mother and father.
Option C is the answer.
