Natural selection
It is the phenomenon by which a favourable trait in a population of a species is selected.
Changing natural conditions exert equal pressure on all the existing species.
The species/organisms which are better adapted to the changing conditions survive and reproduce i.e. selected by nature and species/organisms which cannot adapt perish i.e. rejected by nature
Laws of Mendel
Law of Dominance says that a gene has two contrasting alleles and one always expresses itself in the organism.
It is called the dominant gene and it expresses in any possible combination.
Law of Segregation says that traits get segregated completely during the formation of gametes without any mixing of alleles.
Law of Independent Assortment says that the traits can segregate independently of different characters during gamete formation.
