How does polygenic inheritance differ from mendelian inheritance

Mainly, the number of genes that control traits.

Explanation:

Polygenic inheritance does not follow Mendel's law of dominance. According to Mendel the dominant trait will mask the recessive trait however, this is not always the case. Polygenic inheritance states that traits are controlled by two or more genes and is also dependent on the environment.

Let's take skin color for example. A fair-skinned person will have a child with a dark-skinned person.

Mendelian inheritance would assume that the offspring would either be fair or dark only.

Polygenic inheritance would assume that the offspring would be either fair, dark, or a tone in between, depending on the environment they are in as well.

Hope you understood it.

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.
