a) If the F1 progeny of two purebred organisms (DDEE X ddee) were testcrossed, give the expected genotypes of the progeny, assuming independent assortment. Show your work.

b) If the F1 progeny from (a) were selfed, give the expected ratio of genotypes assuming independent assortment. Show your work.

c) Give the genotype of gametes of a triple heterozygote AaBbDd, assuming Mendel's 2nd Principle.
