A sunflower population has a mean of 100 days to flower (T). Parents with a mean of 90 days to flowering were selected (Ts). The heritablity for the trait is h2 = 0.2 days to flowering. What will be the mean of the population if these parents are crossed?
R = h2S
R = 0.2(90 -100)
R = -2 days
New population = T' = (100 - 2) = 98 days to flowering
