Document Summary

Under directional selection, the advantageous allele will increase in frequency independently of its dominance relative to other alleles (i. e. even if the advantageous allele is recessive, it will eventually become fixed). changes in population genetics that simultaneously favour individuals at both extremes of the distribution. This is one of many processes that can lead to speciation because the now separated populations can"t exchange genes (gene flow doesn"t occur) meaning that the heritable mutations that occur in the populations will not be shared and the populations will diverge and become different species (maybe). a population of organisms that live in different ecological niches which means that they are different species. The females must make a careful selection because they invest a lot of metabolic energy into producing offspring than the males. occurs when an allele is present in either each individual of a population or none of them (ie. the allele frequency reaches either.
