125 progeny were produced from the following cross: aaBbCcDd x AaBbccDD. Assume that all the genes are unlinked, and that the uppercase letters represent dominant alleles.
a) How many offspring are expected to express the dominant phenotype for each gene?
b) how mant offspring are expected to have the genotype aaBBccDd?
c) How many offspring are expected to have the genotype AaBbCcDd?
