LUC BIOL 112 EXAM 1 LABS 11, 12, 13 STUDY GUIDE QUESTIONS AND ANSWERS 2026/2027 |
COMPLETE LAB EXAM REVIEW
small scale evolution (population genetics) - ANS ✔✔changes in ALLELE FREQUENCY in a
population from one generation to the next
large scale evolution (phylogenetics) - ANS ✔✔the descent of different species from a common
ancestor over many generations
population - ANS ✔✔a group of organisms of the same species living and interacting in the
same area
alleles - ANS ✔✔alternative versions of a gene
gene pool - ANS ✔✔Combined genetic information of all the members of a particular
population
allele frequency - ANS ✔✔the proportion of a particular allele in the gene pool
Hardy-Weinberg equilibrium - ANS ✔✔one gene with two alleles, if certain assumptions are
met, allele frequencies will not change from generation to generation in a population
Hardy Weinberg 5 assumptions - ANS ✔✔1. no mutation in the population (no new alleles)
2. no migration into or out of the population (no gene flow)
3. random mating within the population
4. population size large enough to avoid changes due to chance events (no genetic drift)
5. no natural selection, so all phenotypes are equally likely to leave offspring
