Answer 1

Ans. Gene expression and inheritance is different in males and females. An allele which is dominant in one sex can be recessive in another sex.

Males have one Y chromosomes and genes present on this chromosome will be expressed only in male and many of these have no counterparts on autosomes or X chromosomes.

Also some genes are influenced by sex. For example- gene of baldness causes baldness even in heterozygous condition in male but for baldness in female, both allele should be dominant or homozygous dominant.
