Which of the following is an example of polygenic (quantitative) inheritance? a. the ABO blood groups b. Huntington's disease

Inheritance patterns are often more complex than predicted by simple mendalian genetics. When Mendel studied some phenotypic characters, like the human skin color and height, they were found to be an addictive effect of two or more genes on a single phenotypic character. These are called quantitative characters, which usually indicates polygenic inheritance.

The human height is an example of quantitative character, it is controlled by at least 3 genes having 6 alleles. 3 genes with 6 alleles from both parent can give rise to wide range of phenotypic character (heights).

Answer: Example of polygenic inheritance is height in humans.

Explanation:

Polygenic (quantitative) inheritance is a single characteristics or inherited trait that is controlled by two or more genes. It is also called quantitative inheritance. Examples include skin color, human height, weight, hair color.

In plants it include grain color, length of maize or flower size e.t.c.

In animal it include animal size,longetivity or disease resistance.
