Answer 1

Answer: (C), (D)

The correct options are

D multiple allelic

Polygenic inheritance occurs when one characteristic is controlled by two or more different genes. Examples: human height, skin colour, etc.

Multiple alleles are the three or more alternative forms of a single gene (alleles) that can occupy the same locus and code for a single trait. Example: human blood group.
