Document Summary
Reproductive success: likelihood of an individual contributing fertile o spring to the next generation, attributed to two categories of traits. Certain characteristics make organisms better adapted to their environment and more likely to survive to reproductive age. Traits that are directly associated with reproduction such as the ability to nd a mate and the ability to produce viable gametes and o spring. Individuals with bene cial allele are more likely to survive and contribute their alleles to the gene pool of the next generation. 3: over course of many generations, allele frequency of many di erent genes may change through natural selection, thereby signi cantly altering the characteristics of a population. Relative likelihood that a genotype will contribute to the gene pool of he next generation as compared with other genotypes. Measure of reproductive success (not physical prowess) Hypothetical gene with alleles a and a. Tness is w and max is 1. 0 for genotype with highest reproductive activity.
