Question 14.
Answer the following question.
How are the hereditary changes responsible for evolution?
Answer:
Heredity is the transfer of genes from one generation to another generation. However, sometimes sudden changes in genes occur due to a process called mutation. These are heredity changes. Evolution is the gradual change occurring in the living organisms over a long duration. New species are formed due to changes in the specific characters of several generation and are selected by the nature to survive. Thus hereditary changes are responsible for the evolution.
