How is pairing achieved? a. Since all other homologous chromosomes pair, the remaining two chromosomes pair by default. b Pairing proteins are capable of binding to different genes on the X and Y chromosomes, which allows them to pair. c. None of the statements is correct. d. They don't actually pair. Random segregation generally ensures the X and Y chromosomes separate. e.Pseudoautosomal regions that are homologous exist at the tips of both the X and Y chromosomes, and they allow pairing.arrow_forward
