What are three ways natural selection can effect the polygenic traits?
i really like peanut butter jelly
How genes affect characteristics?
It is a polygenic character
Traits that are shaped by many genes are called what?
Traits that are produced by the interaction of several genes are called polygenic traits. Examples of polygenic traits are height and skin color.
When the phenotypes of polygenic traits are represented by a bell shaped curve the?
Many polygenic traits are represented by a bell cure because they are controlled by many genes and result in gradations where each gene has an effect.
What controls a polygenic trait?
two or more genes

If coat color in a rabbit population is a polygenic trait which process might have produced the graph below?
A) Disruptive Selection
What are ways in which natural selection operates on ploygenic traits?
Polygenic? Natural selection usually acts on the phenotype of polygenic traits as they are suites of genes acting in concert to form a trait. If you had a trait, such as height, in two variant brothers then the aggregate would need to be selected for as the genes working in concert, but not equally well, would render different heights in the brothers which would be then visible to natural selection.
What terms describes natural selection that acts against intermediate forms of a polygenic trait to increase genetic variation while not changing the average value of a trait within?
Disruptive selection
What is trait called when it is controlled by more than one gene?
Polygenic Traits
What type two or more genes control a trait?
Polygenic trait
How genes affect characteristics?
It is a polygenic character
Describe three patterns of natural selection on polygenic traits Which one leads to two distinct phenotypes?
One pattern of natural selection polygenic traits is directional selection, in which one end of the spectrum leads to increased fitness and the other end decreased fitness. Disruptive selection is when both ends of the spectrum lead to increased fitness and the middle leads to decreased fitness and it leads to two distinct phenotypes being selected for. It's opposite is stabilizing selection, in which the middle has the best fitness and the two extremes have decreased fitness.
