what is the hereditary genetic material
Genetic material is that substance which not only controls the inheritance of traits from one generation to the next but is also able to express its effect through the formation and functioning of the traits. Components of genetic material which control characters are called genes. Genes are located over chromosomes. In sexually reproducing organisms, an indiÂ­vidual receives one genome or one set of chromosomes (and hence genes) from male parent and a second genome or set of chromosomes from female parent.
