Question

What is the genotypic ratio of a trihybrid cross?​

Answer 1

Answer:

27:9:9:9:3:3:3:1 ratio: As can be seen in the forked line diagram above, a trihybrid cross yields a phenotypic ratio of 27:9:9:9:3:3:3:1. This reflects the phenotypes generated by the 64 genotypic combinations resulting from 8 different male gametes fertilizing 8 different female gametes.
