heredity studies

Heredity - An important result of the reproductive cycle is production of similar featured individuals for generations. The transmission of characteristics through successive generations refers to heredity. These characteristics include all physical, physiological and psychologi..

Heredity and Variation - All living organisms reproduce. Reproduction results in the formation of offspring of the same kind. A pea plant produces only pea plants each time it reproduces. A rat produces only rats. Humans produce only humans. However, the resulting offspring need not and m..

Summary - All these evidences point to the fact that evolution occurs. The exact mechanism of evolution, however, is not yet conclusively proven. But constant study and research in the above fields is continuing for answers. Asexual reproduction results in identical offspring whereas sexu..

. The scientific study of the transmission of hereditary character from one generation to the other is known as genetics. If we look around us, we see different kinds of organisms. The organisms are of different species. Even among the species, there are differences. For example, one cat ..

Physical Basis of Heredity - According to Mendel, the genotype is made of certain structures called factors. The factors controlled the inheritance of all traits. These factors are present in pairs. The factors are now called genes. Thus the physical basis of heredity are the ge..

According to Mendel, the genotype i.e., the combination of genes or the genetic constitution is made of certain structures called factors. The factors controlled the inheritance of all traits. These factors are present in pairs. The factors are now called genes. Thus the physical basis of her..

Haeckel (1834-1919) formulated that 'ontogeny recapitulates phylogeny'. This means that the developmental stages that an organism goes through repeat the evolutionary history of the group to which the organism belongs. Stages in Embryological Development Though it does not explain the mechanism of ..
