In the same population of locusts, the mean wing length is 47 mm, the selection gradient on wing length is β = 0.12/mm, the phenotypic variance for wing length is P = 3.6 mm2 , and the heritability of wing length is h2 = 0.27. In addition, we know that the additive genetic covariance between wing length and leg length is 0.6 mm2 . What is the expected evolutionary change in mean leg length due to selection on wings?

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
