Chapter 24, Problem 5TYK
Summary Introduction
Introduction: Polyploid species arise with the interbreeding of two different species. The hybrid may propagate asexually but they are sterile due to complications in the mitotic division of gametes.

- Give explanation X and Y chromosomes are not homologs, but in meiosis they do pair and segregate in XY organisms to create 50% haploid gametes with an X chromosome and 50% haploid gametes with a Y chromosome. 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_forwardYou come across a pea plant with yellow round peas but you aren't sure about it's genotype. 1. a.

Use one of the genotypes from 'a' and write out a test cross and the predicted progeny. C. Use another of the genotypes from 'a' and write out a test cross and the predicted progeny, clearly indicating how the progeny would be different and in different proportions depending on the genotype from 'a'.arrow_forwardWhat does a bell-shaped curve of a graph indicate?
