hope this helps :)

Answer 2

The correct answer is pleiotropy.

Step-by-step explanation:

The kinds of genes that affect and influence more than one character or trait are known as the pleiotropic genes. This phenomenon is known as pleiotropy or pleiotropism. An illustration of pleiotropy is sickle cell disease or sickle cell anemia. In a specific homozygous condition that is, HbS and HbS, the gene for sickle-cell anemia is lethal, while the generation of sickle cell trait occurs in heterozygous condition, that is, HbA and HbS.
