![]() ![]() Over time, the proportion of individuals with advantageous traits may increase (and the proportion with disadvantageous traits may decrease) due to their chances of surviving and reproducing.Inherited characteristics affect the likelihood of an organism's survival and reproduction.Natural selection and genetic drift act on the variation that exists in a population.Evolution results from natural selection acting upon genetic variation within a population.The Hardy-Weinberg equation describes expectations about the gene pool of a population that isn't evolving, that is large, mates randomly, doesn't experience mutation, natural selection, or gene flow.Evolution is often defined as a change in allele frequencies within a population. The activities focus on the MC1R gene, protein, and receptor, to teach valuable lessons on mutation, selection, and convergent evolution, and to tie together biochemistry, cell communication, and.Environmental changes may provide opportunities that can influence natural selection.Depending on environmental conditions, inherited characteristics may be advantageous, neutral, or detrimental.Over time, the proportion of individuals with advantageous characteristics may increase due to their likelihood of surviving and reproducing.Natural selection is dependent on environmental conditions.Natural selection acts on phenotype as an expression of genotype.Natural selection acts on the variation that exists in a population. ![]() Evolution results from selection acting upon genetic variation within a population.There is a fit between organisms and their environments, though not always a perfect fit.I use the Rock Pocket Mouse with my first year students every year. There is a fit between organisms and their environments, though not always a perfect fit.
