Answer #1

The correct answers is option 2. Pleiotropy is when one gene affects multiple characteristics.

Pleiotropy refers to one gene controlling different phenotypic characteristics of an organism. 6th position of beta chain of haemoglobin generally has glutamic acid which changes to valine which is Controlled by the 11th chromosome which affects RBC, heart, kidney and liver is an example of pleiotropy.

Polygene refers to when one phenotypic feature is controlled by more than one gene. The phenotype of skin color is controlled by 3 genes.
