Answer:
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.
Explanation:
Evolution, in genetic terms, involves a change in the frequency of alleles in a population over time. What are the sources of genetic variation? Three sources of genetic variation are mutation, genetic recombination during sexual reproduction and lateral gene transfer.
Condensation reaction (also called condensation polymerisation or dehydration synthesis) - an example of this is the formation of polypeptides from amino acid monomers. It is typically characterised by the loss of a water molecule during the reaction.
