A population of Drosophila melanogaster is being studied for its response to selection pressure. The initial population mean is 10 cm, and the s\tandard deviation is 2 cm. After 10 generations of selection, the population mean increases to 12 cm. Assuming a heritability of 0.5, calculate the selection differential (S) and the realized heritability \( h^2_r \).

Answer Options

A. S = 2 cm, h^2_r = 0.5
B. S = 4 cm, h^2_r = 0.25
Correct Answer C. S = 6 cm, h^2_r = 0.75
D. S = 8 cm, h^2_r = 0.9
Correct Answer
C
Correct Option:
S = 6 cm, h^2_r = 0.75
