In a species of rat height is a polygenic trait. what does it mean for this trait to be polygenic?

∙ 7y ago
Usually, traits are polygenic when there is wide variation in the trait. For example, humans can be of many different sizes. Height is a polygenic trait, controlled by at least three genes with six alleles. If you are dominant for all of the alleles for height, then you will be very tall.

Why is it possible that a majority of people may display a recessive trait?
A recessive trait can be masked by a dominant trait in individuals who are heterozygous. Thus, a majority of people may appear to display the dominant trait even if they are carriers of the recessive trait. Only when two carriers of the recessive trait have children together is there a chance for the recessive trait to become visible in the offspring.
What does it mean when a trait is recessive?
The principle of excessiveness is defined as the explanation of why one trait will not show over another. If a trait is recessive it will not show when a dominant trait is present.
What is the central force in evolution?
There is no central force, except that anything which does not hinder a gene's chance of reproducing will allow whatever species that gene belongs to live on. If a trait helps a species to survive, that trait will be "selected". Look at it this way, if a particular trait means that some members of a species is less likely to breed than other members, that trait will die out eventually. This could mean that lions which have shorter claws than their fellows, or cheetahs which can't run as fast as their fellows will go hungry, and be less successful in having and rearing cubs which carry their genes. That is not so much a force driving evolution as a force culling those members of a species which are "less fit" for survival than their fellows

Do blue bellied lizards eat?
The "blue bellied lizard" is not a species of lizard. In fact, there are so many species of lizards with this trait that it is too vague for me to confidently answer. I will assume you mean a western United States species of tree lizard of some sort or a lizard of the genus sceloporus. Both are insectivores.
