The mean and variance of plant height of two highly inbred strains (P₁ and P₂) and their progeny (F₁ and F₂) are shown here. Strain Mean (cm) Variance _ P₁ 34.2 4.2 P₂ 55.3 3.8 F₁ 44.2 5.6 F₂ 46.3 10.3 Calculate the broad-sense heritability (H²) of plant height in this species.

Hello everyone here We have a question asking us which of the following selection process is preferred? For traits with high heritability on one's records. We have a family selection. This selection process involves selecting individuals from a population based on their family history. This is not typically used when selecting traits that have high heritability. So A. Is incorrect. Be individual selection. This involves selecting individuals from a population based on their performance or phenotype. So B. Is incorrect. So now that we know that A. And B. Are incorrect, that makes D also incorrect. So our answer is C. Mass selection which is a process that involves selecting individuals from a population based on their overall performance or genotype. This is often used when selecting traits that have high heritability. When hair ability is high mass selection will be effective because the best parents can be identified reliably on a single individual basis. So our answer is C. Mass selection. Thank you for watching. Bye.
