Question

State whether the following statement is true or false.

No genes are common to both the X and Y-chromosomes.

Answer 1

This statement is false.

Explanation:

While the X and Y chromosomes are largely different and have distinct sets of genes, there are regions known as the pseudoautosomal regions where genes are common to both the X and Y chromosomes and can undergo recombination. Thus, some genes are shared between the X and Y chromosomes, enabling pairing and segregation during meiosis in males.
