Question

What is the phenotype of an individual - XHY?

Answer 1

The genotype is the set of genes in our DNA which is responsible for a particular trait. Thephenotype is the physical expression, or characteristics, of that trait. For example, two organisms that have even the minutest difference in their genes are said to have different genotypes.

Answer 2

Answer:

The correct answer would be a "male with non-hemophilia".

Hemophilia is X-linked recessive disorder which affects the clotting properties of the blood.

It is caused by mutation in gene responsible for synthesis of clotting factor VIII (hemophilia A)  and/or clotting factor IX (hemophilia B).

The allele of this gene is represented by "H" and "h".

"H" represents the dominant allele which leads to the normal production of clotting factor and "h" represents the recessive allele which leads to the development of hemophilia.

As it is X linked, two copies of h need to be present in females in order to develop hemophilia whereas single copy of h is enough to produce the effect as male carries only single X chromosomes.

Hence, the genotype of male with hemophilia would be $X^{h}Y$.

The genotype of male without hemophilia would be $X^{H}Y$.

The genotype of female with hemophilia would be $X^{h}X^{h}$.

The genotype of female without hemophilia would be $X^{H}X^{h}$ or $X^{H}X^{H}$
