WebCertain characteristics are expected of a trait inherited in polygenic/multifactorial fashion and showing discontinuous variation. Traits fulfilling most or all of these criteria can be deduced to be inherited in polygenic/multifactorial fashion, with recurrence risks of 1–5% even in the absence of empiric data. 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. So, the correct option is ‘Polygenic trait is controlled by multiple ...

WebEye colour. Eye colour is also one of the most important polygenic traits examples in humans. The melanin composition in the front part of the iris is responsible for the eye colour. The more melanin deposited the darker colour is resulting, hence dark brown or black eye colour has more melanin compared to hazel or green eyes. WebJan 4, 2024 · The standard population genetic approach of ascribing a selection coefficient to an individual locus yields tractable models but does not always extend easily to polygenic traits.
