Chapter 14, Problem 5GP
Human females have two X chromosomes (XX); males have one X and one Y chromosome (XY).
- a. With respect to X chromosome alleles, how many different types of gametes can a male produce?
- b. If a female is homozygous for an allele on an X chromosome, how many types of gametes can she produce with respect to that allele?
- c. If a female is heterozygous for an X chromosome allele, how many types or gametes can she produce with respect to that allele?

AabbCcDdEeFFGgHh x AaBbCcDdEEffggHH,
a) how many possible gametes can the first individual produce?
b) what proportion of the offspring will phenotypically resemble the first parent?
c) what proportion of the offspring will genotypically resemble the second parent?
d) how many phenotypes can be expected from the cross?
