Solution Summary

Homology among X and Y chromosome is not possible as they are not absolutely homologous to each other. However, in plants very small portion of X and Y chromosomes are homologius to each other.

Solution Preview

The non-recombining region of the Y chromosome (NRY), which comprises 95% of the chromosome, does not undergo sexual recombination and is present only in males. An understanding of its biological functions has begun to emerge from DNA studies of individuals with partial Y chromosomes, coupled with ...
