Consider the following cross

aabbcc x aabbcc

you can assume the 3 genes assort independently and that the capital letters mark alleles associated with fully dominant phenotypes (just what mendel showed us).

what is the probability that the first born offspring of this cross will show the dominant phenotype for all three genes?

a. 3/4
b. 1 = all of the offspring will show just the dominant phenotypes
c. 27/64
d. 3/8
e. 9/64
f. 1/8
g. 9/32
