According to this statement, the frequency of a trait’s genotypes, written as p2, 2pq, and q2, should sum to 1. For 10 points each:
[10m] Name this doubly-eponymous statement which states that allele and genotype frequencies in a population will remain constant between generations without the presence of evolution.
ANSWER: Hardy–Weinberg equilibrium [accept “model,” “theorem,” or “law” in place of “equilibrium”; accept HWE]
[10e] One assumption under Hardy-Weinberg equilibrium is that this quantity is infinite. This quantity is the number of individuals in a population, and its upper limit in a logistic growth model is called the carrying capacity.
ANSWER: population size [accept N; reject “population”]
[10h] The model’s assumption of an infinite population is to negate the effects of genetic drift, a special case of which is this effect. In this effect, genetic variation is lost when a new population is established by a small group.
ANSWER: founder effect
