BIO 351 Test #2 2025 Questions and
Answers 100% Pass
population genetics - ✔✔changes in relative abundance of genetic variants in a
population can be tied to changes in relative abundance of genetic variants that
influence them
evolution - ✔✔change across generations in the frequencies of alleles
population - ✔✔group of interbreeeding individuals and their offspring
gene pool - ✔✔all of the different genes in an interbreeding population
genetic drift - ✔✔decline of the relative frequency of a genotype within a given
population, random process that does not lead to adaptations but rather changes in
allele freq., more powerful evolution mechanism if across multiple generations
Hardy Weinberg Equilibrium - ✔✔genotype frequencies in a population remain
constant between generation in the absence of disturbance by outside factors, used as a
null model
Hardy Weinberg Conclusions - ✔✔1. Allele frequency in a population will not change
2. If allele frequency given by p+q=1 then it holds that p^2 +2pq+ q^2
Hardy Weinberg Assumptions/Conditions - ✔✔1. No selection: some genotype cannot
have a better chance than others, contribute equal # of gametes
2. No mutation: no new alleles
