consists of all genes that are present in a population
number of times an allele occurs in a gene pool compared to total number of elleles in the pool for that gene
Single Gene Trait
trait controlled by one gene
traits controlled by two or more genes
form of natural selection where individuals in middle of curve have higher fitness than individuals at either end of the curve
form of natural selection where individuals at one end of fitness curve have higher fitness than individuals in the middle or other end of the curve
natural selection where individuals at upper and lower ends of the curve have higher fitness than individuals in the middle
random change in allele frequency
change in allele frequency following a dramatic reduction of population size
allele frequencies change because of migration of a small sub group of a population
allele frequencies in gene pools aren't changing
allele frequencies in a population should remain constant unless one or more factors cause the frequencies to change
select mates by size, strength, or coloration
