Identify three types of natural selection for a polygenic trait.
kaheart [24]

Answer:

A polygenic trait can be described as a physical trait which is influenced by more than one gene.

The three types of selection for a polygenic trait are:

1) Directional Selection: In a directional selection, one of the phenotype is favored in an ecosystem. As a result of this favoring, the allelic frequency changes and shifts in favor of this particular trait.

2) Stabilizing selection: It is a type of natural selection in which the intermediate trait is favored. The population carries a middle trait in abundance.

3) Disruptive Selection: Disruptive trait is a type of natural selection in which the traits on the extreme sides are favored. The intermediate traits are less favored.

The moon gives off a reddish appearance during this time because the only light reaching the moon and reflected off of its surface is the light refracted by the Earth's atmosphere (the same reason a sunrise/sunset appears reddish).

A totally eclipsed full moon is also known as a Blood Moon because of it's colour
