A type of butterfly comes in three colors: red, blue, and purple. Their color is controlled by a single trait gene with two alleles that display codominance. The R allele codes for red pigment and the B allele codes for blue pigment. If two heterozygous butterflies from this population mated, what would be the predicted genotypes of their offspring? Hint: draw a Punnett square. A) 50% BB, 50% RR
B) 100 % BR
C)25% BB, 50% BR, 25% RR
D) 75% BB, 25% RR
E) 75% RR, 25% BB
