|
selective breeding

adaptation

sepeciation

evolution

Explanation:
Detailed explanation-1: -Evolution is the process by which populations of organisms change over generations. Genetic variations underlie these changes.
Detailed explanation-2: -Populations (or gene pools ) evolve as gene frequencies change; individual organisms cannot evolve. Variation in populations is determined by the genes present in the population’s gene pool, which may be directly altered by mutation.
Detailed explanation-3: -Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error). Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations.
