Heredity and Evolution. We have seen that reproductive processes give rise to new individuals that are similar, but subtly different. We have discussed how some amount of variation is produced even during asexual reproduction. And the number of successful variations are maximised by the process of sexual reproduction.

Traits are the genetically determined characteristics which are transferred from both the parents to their offspring through the genes during the sexual mode of reproduction. DNA is the carrier of this genetic information and is found in the chromosomes of our cells.
Evolution is generally defined as the changes in the genetic features of the progeny over successive generations. Charles Robert Darwin, a naturalist, geologist, biologist, and is best known for his contributions to the science of evolution. Based on his theories and ideas on Evolution, he is considered as the father of Evolution. According to Char...
Charles Darwin, an English biologist, was the first person to describe the theory of evolution. In his book, On the Origin of Species, he has explained that all living organisms change their physical and anatomical structure over a long period of time to adapt to the changing environment. He also proposed that this change is by natural process and ...
Evolution helps us to better understand how a new species come into existence, how it becomes extinct, and various other aspects such as their habitats and behaviour. It can also be observed that there is an inbuilt tendency for variation during the reproduction process and these are mainly caused by the combining of genetic material from two paren...
