Quiz: How Much You Know About Important Terms Used In Genetics?
Let’s start the quiz
A branch of biology which deals with the study of genes, genetic variation, and heredity in living organisms is called Genetics. The word Heredity is derived from the Latin word Hereditatem which means the condition of being an heir. It is the transmission of characters from the parents to the offspring. The physical basis of heredity are factors or genes which are passed from one generation to the next in the form of the chromosome. The chemical basis of heredity are DNA, genetic material present in the chromosome. So take this quiz and check your knowledge related to the terms used in genetics.
