this shows that during sexual reprouduction u will get differnt genes from differnt parents and more and more combos so the more evolution there will be. and the more changes in the way traits and features r made and loks.
Answer:
Evolution can also occur as a result of genes being transferred from one population to another. This gene flow occurs when there is migration. The loss or addition of people can easily change gene pool frequencies even if there are no other evolutionary mechanisms operating. Also, the effect of gene flow is to reduce genetic differences between populations, thereby preventing or delaying the evolution of the populations in different geographical areas into separate species of the pathogen. Gene flow and natural selection are two central, and usually opposing, evolutionary forces: gene flow distributes, homogenizes, and maintains genetic variation that can act as the 'stuff of evolution', while natural selection reduces genetic variation to the variants that favor survival and reproduction
Explanation:
In biology, evolution is the change in the inherited traits of a population from generation to generation. Evolution occurs when these heritable differences become more common or rare in a population, either non-randomly through natural selection or randomly through genetic drift.
The frequency of alleles of importance in a population is affected by gene flow from other populations. The effect of gene flow is to reduce genetic differences between populations, thereby preventing or delaying the evolution of the populations in different geographical areas into separate species of the pathogen.
