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 … WebJul 5, 2024 · Traits like these that display a wide range of variation result from the interaction of several genes, and are called polygenic traits (poly means “many,” and genic means “genes”). In order to understand why polygenic traits lead to such a range of variations, try imagining each gene as a light with two light bulbs.
