WebWe first examine the impact of genetic drift on the evolutionary fate of a newly arisen mutation. Let A symbolize the group of all the old alleles at an autosomal locus, and let a be a newly arisen mutation at this locus that is initially present in only a single individual with the new genotype Aa.We initially regard this individual as a self-compatible, random … WebA mutation may be neutral. and have no effect. For example, the protein that a mutated gene produces may work just as well as the protein from the normal gene. A mutation … WebMicroevolution is the change in allele frequencies that occurs over time within a population. This change is due to four different processes: mutation, selection (natural and artificial), gene flow and genetic drift.This change happens over a relatively short (in evolutionary terms) amount of time compared to the changes termed macroevolution. list of care homes in cambridgeshire
