Answer:
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. Through heredity, variations between individuals can accumulate and cause species to evolve by natural selection. The study of heredity in biology is genetics.
In humans, eye color is an example of an inherited characteristic: an individual might inherit the "brown-eye trait" from one of the parents.[1] Inherited traits are controlled by genes and the complete set of genes within an organism's genome is called its genotype.[2]
The complete set of observable traits of the structure and behavior of an organism is called its phenotype. These traits arise from the interaction of its genotype with the environment.[3] As a result, many aspects of an organism's phenotype are not inherited. For example, suntanned skin comes from the interaction between a person's phenotype and sunlight;[4] thus, suntans are not passed on to people's children. However, some people tan more easily than others, due to differences in their genotype:[5] a striking example is people with the inherited trait of albinism, who do not tan at all and are very sensitive to sunburn.[6]
