WebJan 19, 2024 · To improve on a polygenic trait, we need genetic variation to select for. Instead of selecting a single best dog, we can select a subpopulation of dogs that are all faster than average. We will then use the genetic variation in those dogs, and the random inheritance of that variation in the offspring, to push racing performance in the direction of … WebApr 18, 2024 · Intuitively this occurs because if population B has a larger value of an ascertained polygenic score than population A, then the ascertained trait-increasing alleles have by chance drifted up in population B (compared to A) and this imbalance will have induced directional selection for the rest of the trait-increasing alleles to decrease their …
WebNov 20, 2024 · The human aging process is influenced by genetic and environmental factors, which makes it one of the most complex traits to study (1, 2).Previous studies estimated that the heritability of life span up to approximately 70 years of age ranges from 10% to 25% (3, 4).However, to reach higher ages, we become increasingly dependent on the favorable … WebC.Height, weight and skin colour are polygenic – True, because many genes control variety of phenotypes in the living organisms. D.Polygenic traits is controlled by multiple alleles – False, because many genes control one trait. It is called Polygenic inheritance.
