A trihybrid cross is made between two yeasts, both with genotype AaBbCc. What proportion of the offspring will be of the genotype aabbcc?

A

0

B

`(1)/(4)`

C

`(1)/(16)`

D

`(1)/(64)`

Text Solution

Verified by Experts

The correct Answer is:
D
The frequency of getting aa of bb or cc separately is `(1)/(4)`. Therefore, probability of offspring having all three of these homozygous pairs is `((1),(4))^(3)=(1)/(64)`
