Explain three ways by which genes enter in a particular population
Answers
Answer:
1)Speciation: speciation is the splitting of one species into two or more species or transformation of one species into a new species over period of time due to geographical barrier or reproductive isolation.2) gene flow: it is the movement of alleles or genes between population of the same species by migration of individual which can interbreed among themselves.3) genetic drift: In small populations, accidents can change the frequency of some genes in a population,even if these give no survival advantage to the possessors . This phenomenon is called genetic drift.Genetic drift can be defined as change in gene frequency which occurs by chance in a small population
