The ability of an individual genotype or phenotype to both survive and reproduce (cid:1) W = the average contribution of an average individual of a certain genotype to the gene pool of the next generation. W is relative to other genotypes or phenotypes in the same population. No sampling bias, no effect from chance events, no genetic drift. No alleles coming in from the outside, no migration. No new alleles are spontaneously arising in the population. All alleles have an equal probability of surviving. Violations of these assumptions = evolution (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) Selection occurs when a particular genotype does not survive or reproduce in the same proportion as others (cid:1)
