Please answer ASAP as I have my board exam tomorrow. Plus, make it easy.
Answers
Explanation:
Natural selection- Organism which are dominant and are able to produce their offspring and are reproductively healthy survives and rest are eliminate by nature so nature select the best.
genetic drift- Due to some reason some part of population gets seperated suppose on either side of mountain and then evolve this genetic drift.
Hope it helps you out
Answer:
i)Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
ii)Genetic drift is the process by which deviations in expected allele frequencies develop in finite populations over time as a function of statistical sampling of genes from one generation to the next (as opposed to deviations that may develop in finite populations due to selection, mutation, or admixture).
