This Chapter 1 from Part 2 Science of Class 10 mainly focuses on the concepts of Heredity and Evolution. 2. 2. It is seen that living organisms have the ability to transfer the characters that are acquired to the next generation and this is known as the ancestry of acquired characters. Genetic drift : It is the random change in the frequency of alleles (gene pair) in a population over successive generations. Natural selection : The process by which nature selects and consolidate those organisms which are more suitable adapted and possesses favourable variations. • It is based on the idea that changes in DNA during reproduction are the basic events in evolution. ii) Evolution of feathers:-Feathers were first developed in dinosaurs and used for protection from cold. These are the organs that have same basic structural plan and origin but different functions. Homologous organs provides evidence for evolution by telling us that they are derived from the same ancestor.

(i) When RRyy was crossed with rrYY in F1 generation all were Rr Yy round and yellow seeds. Each species develop within specific geographical conditions and has different food, habitat, reproductive ability and period. Meanwhile, inside dead bodies of plants and animals, the ratio between C-14 and C-12 modifies continuously instead of remaining constant because C-12 is non-radioactive. Darwin did not give any explanation about useful and useless modifications. ii) Evolution of feathers :- Feathers were first developed in dinosaurs and used for protection from cold.
