Document Summary

Gen: that which produces hetero-: different inter-: between; among intra-: within; internal mono-: one; single; alone morph-: form poly-: many. Study of genes and genotypes in a population extent of genetic variation want to know: How it changes over the course of many generations. Helps us understand how genetic variation is related to phenotypic variation. Set of alleles that determines (in part) the expression of a particular trait. B- dominant, b- recessive (bb= blue eyes, bb or bb= brown eyes) Physical (or biochemical) expression of a trait based on genes + environment. All of the alleles for every gene in a given population. Study genetic variation within gene pool & how variation changes from one gen to the next. Emphasis is often on variation in alleles between members of a population. Group of individuals of the same species that occupy the same environment and can interbreed with one another.
