Question

total number of phenotypes and genotypes in F2 generation of a trihybrid cross would be ​

Answer 1

Answer: 8.

Explanation: When we have to calculate the number of phenotypes in a cross, we use 2^n , where n= 1, 2, 3, etc.

For a monohybrid cross, n= 1, and number of phenotypes = 2^1= 2.

For a dihybrid cross, no. Of phenotypes = 2^2 = 4.

For trihybrid cross, 2^3= 8.

Answer 2

Answer:

phenotypic =27:9:9:9:3:3:3:1

genotype=64
