Homologous organs are organs which are similar in structure and origin but have different functions in different organisms. He was known as Father of genetics. Hence, all the options are examples of homologous organs. life on earth. In this chapter we will learn the mechanism by which variations are created and inherited. Thus, variations which are advantageous to an organism will help him to survive as they will help in natural selection. For example, the wings of a bird and a bat are similar in function but this similarity does not mean that these animals are more closely related.

A brother and his cousin are also related but less than the sister and her brother. Thus, the above example suggests that the fossils found closer to the surface of the earth are more recent ones than the fossils present in deeper layers. Thus he concluded that in a contrasting pair of characters one character is dominant and another is recessive. 10 Science Chapter 9 Heredity and Evolution Intext questions and exercises question answers are given below in English and Hindi Medium updated for academic session 2020-21.
