Someone who actually know the answerhow can a polygenic trait be easily identified? the presence of the polygenic trait masks the other possible alleles involved. there are only two possible phenotypes for the trait. the graphing of the possible phenotypes results in a bell curve. the environment has a greater influence on the trait.

Answer;

The graphing of the possible phenotypes results in a bell curve.

Explanation;Polygenic traits are traits that are determined by more than one gene. These types of traits have many possible phenotypes that are determined by interactions among several alleles.Examples of polygenic traits are skin color, eye color, body shape, height and weight among others.Polygenic traits tend to result in a distribution that resembles a bell-shaped curve, with few at the extremes and most in the middle. In the bell-shaped distribution individuals that inherit various combinations of dominant and recessive alleles fall in the middle of the curve.  Individuals who inherit all dominant alleles or all recessive alleles fall at ends of the curve.
