What is mean heredity and evolution

Solution

Dear Student,
1. Heredity is the passing of traits to offspring (from its parent or ancestors). This is the process by which an offspring cell or organism acquires or becomes predisposed to the characteristics of its parent cell or organism. Through heredity, variations exhibited by individuals can accumulate and cause a species to evolve. The study of heredity in biology is called genetics, which includes the field of epigenetics.

2.Evolution (also known as biological, genetic or organic evolution) is the change in the inherited traits of a population of organisms through successive generations.This change results from interactions between processes that introduce variation into a population, and other processes that remove it. As a result, variants with particular traits become more, or less, common. A trait is a particular characteristic—anatomical, biochemical or behavioural that is the result of gene–environment interaction.
