How do genotypes affect phenotypes

WebHuman phenotypes—and phenotypes of other organisms—also vary because they are affected by the environment. For instance, a person may have a genetic tendency to be underweight or obese, but his or her actual weight will depend on diet and exercise (with these factors often playing a greater role than genes). WebMicroevolution is a change in the frequency of gene variants, alleles, in a population, typically occurring over a relatively short time period. Population genetics is the field of biology that studies allele frequencies in populations and how they change over time. Allele frequency refers to how common an allele is in a population.
