Question
A scientist is researching oil content of seeds from a new plant species named R. artificial. The average oil content from plants in her lab population is 52%, and she has determined the narrow sense heritability (h^2) is 0.60. If she randomly mates individuals with 70%, 71%, 72%, 73%, and 74% seed oil content what is the expected response to selection (R)?

Answer:
The correct answer is – 12%
Explanation:
Given:
Mean of the population – 0.52
Narrow sense heritability or h^2 – 0.6
The expected response of selection or R = ?
Solution:
The average oil content in the selected individuals – 0.7, 0.71, 0.72, 0.73, 0.74
And, the mean of these selected individuals = (0.7 + 0.71 + 0.72 + 0.73 + 0.74) / 5
= 0.72
Formula:
S = Average of selected individuals – Average of population
= 0.72 – 0.52
= 0.20
R = h^2 x S
R = 0.6 x 0.2
= 0.12
= 12%
Thus, the correct answer is – 12%
