what is the pseudoautosomal region?

A. the region on the Y chromose where the male-determining gene is found

B. The Region on the X chromose wwhere the female-determining gene is found

C. A region on the Y chromose where the gene, when mutated, causes androgen insensitivity syndrome

D. A region at which the X and Y chromosomes both have copies of the same genes

E. A region at which the X and Y chromosomes differ in their genes.

Solution

D. A region at which the X and Y chromosomes both have copies of the same genes

pseudoautosomal regions are the homologous genes on the X and Y chromosomes. A male contain two copies of these genes one on X and one on Y. Females have them on each of their X chromosomes. These genes exhibit an autosomal pattern of inheritance.
