NEET BIOLOGY

Detailed explanation-1: -From TEDEd, there’s a five finger trick for understanding and remembering the five processes-small population, non-random mating, mutations, gene flow, adaptation-that impact evolution (ie. the changes in the gene pool of a population from generation to generation).

Detailed explanation-2: -They are: mutation, non-random mating, gene flow, finite population size (genetic drift), and natural selection.

Detailed explanation-3: -An adaptation is any heritable trait that helps an organism, such as a plant or animal, survive and reproduce in its environment.

Detailed explanation-4: -The next finger is the ring finger. This finger should remind you of mating, because a ring represents a couple. If individuals choose a mate based on their appearance or location, the frequency may change.
