Document Summary
Why is gene2c varia2on important: total amount of gene5c varia5on affects the evolu5onary poten5al, inbreeding decreases fitness in individuals because they are not gene5cally diverse, it affects individual and popula5on level fitness, quan5fying gene5c varia5on. Absolute fitness (cid:894)w(cid:895) is defi(cid:374)ed as the (cid:374)u(cid:373)(cid:271)e(cid:396) of offsp(cid:396)i(cid:374)g p(cid:396)odu(cid:272)ed o(cid:448)e(cid:396) a(cid:374) i(cid:374)di(cid:448)idual"s life5(cid:373)e, it"s life5me reproduc5ve success. Rela2ve fitness is defined as the measure of biological fitness expressed as the ra5o of the absolute fitness of an individual. It is the comparison of fitness levels of an individual or a par5cular genotype to the fittest genotype of that par5cular popula5on. All the other genotypes would be: w = w/wmax: how the dominance status of alleles affects the response to selection. If there is a situation where there is a strong selec5tion towards one allele, that allele will disappear from the population fairly quickly.
