Question

Stickleback fish are collected from a lake in Alaska. 600 from the sample are spineless, which is a recessive trait in the fish. 80 of the fish collected have spines. Calculate:

Answer 1

Frequency of spinal trait in the population = 0.11

Step-by-step explanation:

Given:

Total spineless trait = 600

Number of spinal trait = 80

Find:

Frequency of spinal trait in the population

Computation:

Total population = Total spineless trait + Number of spinal trait

Total population = 600 + 80

Total population = 680

Frequency of spinal trait in the population = Number of spinal trait / Total population

Frequency of spinal trait in the population = 80 / 680

Frequency of spinal trait in the population = 0.11
