In a species of rat height is a polygenic trait. what does it mean for this trait to be polygenic?
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.
Should help students for the year 2022.

Hope it helped!

What does polygenic mean?
here i used example as, plolygenic genes to explain polygenic one of a group of nonallelic genes that together control a quantitative characteristic in an organism. in other words mean: a group of genes, that determines a number of characeristics of an organism= its phenotype. (phenotype= appearance i.e blue eyes, blond hair) so it says, its genes (more than one), that decides how u are going to look like. foe example : blue eyes, red hair, big, small, etc...

Why is it possible that a majority of people may display a recessive trait?
It is possible for many people to display a recessive trait because the people have two recessive genes. Dominant simply means it will trump a recessive gene, it does not mean it is the most widely seen gene in a species.
What does human trait mean?
A human trait refers to a characteristic or feature that is specific to or commonly found in humans, such as empathy, language abilities, or upright posture. These traits help define the uniqueness of human beings as a species.
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 does ancestral trait mean?

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.
