A Mendelian Cross for a Three-Gene Trait is Expected to Yield

Question

A Mendelian cross for a three-gene trait is expected to yield ________ F2genotypes.
A)4
B)16
C)27
D)64
E)265

Accepted Answer

In a Mendelian cross involving three genes, each with two alleles, the number of possible F2 genotypes is calculated as 2^3 (for each gene) raised to the power of 2, resulting in 3^3 = 27 genotypes.

A Mendelian cross for a three-gene trait is expected to yield ________ F2 genotypes.

A Mendelian cross for a three-gene trait is expected to yield ________ F₂ genotypes.
