A scientist is researching oil content of seeds from a new plant species named R. tificial. The average oil content from plants in her lab population is 52%, and she has determined the narrow sense heritability (h²) 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)? A) 31.2% B) 12% C) 6% D) 72% E) 24%

Question

The expected response to selection (R) is calculated using the formula R = h² * S, where S is the selection differential. The average selected oil content is 72%, and the population mean is 52%, so S = 72% - 52% = 20%. Therefore, R = 0.60 * 20% = 12%.
