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..
