Given the parents AABBCc × AabbCc, assume simple dominance for each trait and independent assortment. What proportion of the pro

Anit [1.1K]

Answer:

3/4

Explanation:

If we assume simple dominance and independent assortment for each trait, we can use Mendel's Law of Segregation to predict the phenotypic proportions in the offspring of the parental cross AABBCc x AabbCc.

AA x Aa

F1 genotypes: 1/2 AA, 1/2 Aa
F1 phenotypes: all A

BB x bb

F1 genotypes: 1 Bb
F1 phenotypes: all B

Cc x Cc

F1 genotypes: 1/4 CC, 2/4 Cc, 1/4 cc
F1 phenotypes: 3/4 C, 1/4 cc

We want to know the proportion of progeny with all dominant phenotype (A_B_C_). Since the genes are independent, we can multiply the probabilities of each gene to obtain the overall probability of having a ABC progeny:
