Ans 13. The X linked recessive disorders would be more common in male as compared to female. A male comprises of a X and a Y chromosome. The Y chromosome doesnt contain most of the genes from the X chromosome, hence as a result of which the recessive traits would be expressed in case of male as compared to females.
Ans 14. The X linked dominanr disorder would be more common in females as compared to males. The females posses a two chance to recieve an affected chromosome or a mutant allele. The hemizygous male wont survive incase of dominant X linked disorder and would perish.
