What is the difference between mendelian inheritance and polygenic inheritance?

In: Genetics [Edit categories]

Answer:

In Mendelian inheritance the allele has a one to one effect on the phenotype. A polygenic effect is given when many genes contribute in an additive fashion to the phenotype. Height is such and may have as many as eight genes contributing to the effect. Behavior is also of this type. Eye color is more Mendelian in nature.
