Question

5. ( true / false ) Because they are different in size and gene content, X and Y chromosomes don’t pair during meiosis (1 point). 6. Development of phenotypic dimorphism (secondary sexual characteristic) in mammals is controlled because of (1 point): A. The chromosomes an individual has. B. Genes an individual inherits (SRY genes). C. Hormones an individual has. D. Signal from the cytoplasm of the mother. 7. If an individual had two X chromosomes and only one Y chromosome, we’d expect them to develop as ( male / female ) (1 point). 8. If a Drosophila fly had two X chromosomes and three Y chromosomes, what sex would expect that fly to be (1 point).
