According to Mendelian genetics, what phenotypic ratio of the offspring do you expect when you do a dihybrid cross, crossing two individuals that are heterozygous in two distinct traits (AaBb)?

A

All offspring individuals will have both dominant phenotypes ( A-B-).

B

All offspring individuals will have both recessive phenotypes (a-b-).

C

The offspring individuals will have either both dominant phenotypes (A-B-) or both recessive phenotypes (a-b-) in a 3:1 ratio.

D

The offspring individuals will have either both dominant phenotypes (A-B-) or both recessive phenotypes (a-b-) in a 1:1 ratio.

E

The offspring individuals will be either dominant for phenotype A only (A-bb) or dominant for phenotype B only (aaB-) in a 1:1 ratio.

F

The ratio of offspring individuals having both dominant phenotypes (A-B-), compared to those dominant for phenotype A only (A-bb), compared to those dominant for phenotype B only (aaB-), compared to those recessive for both phenotypes (aabb), is 1:1:1:1.

G

The ratio of offspring individuals having both dominant phenotypes (A-B-), compared to those dominant for phenotype A only (A-bb), compared to those dominant for phenotype B only (aaB-), compared to those recessive for both phenotypes (aabb), is 9:3:3:1.
