• B. These are generally pleiotropic
• C. They are present on the same locus
• D. All of the above

Answer 1

The correct option is D All of the above

Polygenic inheritance describes the inheritance of traits that are determined by more than one gene. Polygenic traits have many possible phenotypes that are determined by interactions among several alleles present on the same locus. This is responsible for multiple characters. Examples of polygenic inheritance in humans include traits such as skin colour, eye colour, hair colour, body shape, height, weight etc.
