A
inherited trait
B
acquired trait
C
recessive trait
D
ancestral trait
Explanation: 

Detailed explanation-1: -Heredity is a process in which organisms acquire characteristics from their parents. These characteristics are called traits. Every individual is unique because they have a unique set of traits. The traits which are transmitted by the parent to its offspring during the process of fertilization are inherited traits.

Detailed explanation-2: -Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.

Detailed explanation-3: -Instead, they usually mean genes being passed on from parents to children. This is known as “heredity” or “inherited genes."

Detailed explanation-4: -The traits are inherited through genes. Genes code for proteins which decide all the traits like eye colour, height etc. Genes are a basic unit of heredity and are located on the chromosomes. During gamete formation, the chromosomes carrying genes segregate resulting in the inheritance of traits.
