GeneticsThe science of heredity or genetics is the study of two inconsistent elements of nature: heredity and variation. The process of transmission of characters from one generation to the next, either by gametes- sperms and ova- in sexual reproduction or by the asexual reproductive bodies in asexual recreation, is called inheritance or heredity. Heredity is the reason for resemblances between individuals.

This is the factor that siblings with the very same parents resemble each other and with their moms and dads. Variation is the reason for distinctions between individuals. This is the reason that brothers and sisters who do resemble each other are still unique people.

Hence, we have no trouble in acknowledging the distinctions between sisters, for example, and even identical twins are recognized as distinct individuals by their parents and friends. The science of genes tries to describe the system and the basis for both resemblances and differences between associated people. It also tries to discuss the phenomenon of evolution and cytodifferentiation.

What is Genetics. The life science which handles the mechanism of heredity and reasons for variations in living beings (viruses, bacteria, plants, and animals) is referred to as genetics. The word genetic was derived from the Greek root gen which means to become or to grow into and it was coined by Bateson in 1906 for the research study of the physiology of heredity and variations.
