Incomplete genetic linkage of three genes in a trihybrid produces eight genetically different gamete genotypes.How many genotypes are produced in a four-gene cross with incomplete genetic linkage?
A)4
B)8
C)16
D)20
E)24

Question

Quizplus · Accepted Answer

In a trihybrid cross, the possible gamete genotypes are 2³ = 8 due to incomplete genetic linkage of three genes. In a four-gene cross, the possible gamete genotypes would be 2⁴ = 16 due to the independent assortment of the four genes during meiosis. Therefore, the answer is C)16.
