Question

What is the phenotypic ratio of trihybrid cross?

Answer 1

Trihybrid cross:

1. With three unlinked genes, each parent can produce 8 different types of gametes, which generates 64 possible genotypic combinations.
   
2. The phenotypic ratio of the trihybrid cross is 27:9:9:9:3:3:3:1.
3. These are the phenotypes or the visible characters of the offsprings at the end of trihybrid cross.
