4. Two organisms, one of homozygous dominant genotype and the other homozygous recessive, are mated to produce an F1 generation that is then self-fertilized. If there are 6 loci being studied and there is independent assortment: (6 pts)

a)    How many different genotypes will occur in the F2 generation?

b)   What proportion of the F2 genotypes will be homozygous dominant for all 6 loci?

c)    If the initial cross occurred between AAbbccDdEeFf X AabbccddeeFF, would you change your answer to a and/or b? Explain and assume the 6 loci are labelled A through F.
