Document Summary
Microevolution: genetic variation & mutation & hardy-weinberg principle, define key terms: population, microevolution, phenotypic variation, qualitative and quantitative variation, mean/average value of characteristic. Population: all individuals of a single species that live together in the same pale and time. Microevolution: small- scale genetic changes within populations, often in response to shifting environmental circumstances or chance events. Qualitative variation (discrete); variation that exists in two or more discrete states with intermediate forms often being absent. Ex flower color either purple or white; blood type a or b or ab, you are either 6 foot or 5 foot , nothing else. Quantitative variation (continuous): variation that is measured on a continuum rather than discrete units or categories. Individuals differ in small, incremental ways ex in my biology class height, weight, toe lengths, # hairs on heads. Variation is important because it is a strong contributor to evolution. Through variation within a population individuals vary in genetics.
