Gametes 1. The genes for orange and black fur in cats are on the X chromosome. An orange female cat mates with a black male. The resulting litter includes a male calico (orange and black) kitten that, when mature, proves to be sterile. Karyotype analysis reveals the male kitten is XXY. A. Illustrate below how the kitten's genotype could have arisen due to nondisjunction. You only need to show the sex chromosomes. You may use symbols or lines as chromosomes. (2 pts) Interphase DNA replication After Meiosis | O O 1 2 3 4 B. If cats have 38 chromosomes, show on your drawing how many chromosomes total are present in each of the gametes. Write it in the spaces provided for you below the drawing. (2 pts) C. In which parent did nondisjunction occur? (1 pt) Gametes 1. The genes for orange and black fur in cats are on the X chromosome.
