Student Exploration: Hardy-Weinberg Equilibrium Vocabulary: allele, genotype, Hardy-Weinberg equation, Hardy-Weinberg principle, heterozygous, homozygous, incompletely dominant, Punnett square Prior Knowledge Questions (Do these BEFORE using the Gizmo.) A bird’s feather color is controlled by two alleles, D (dark feathers) and d (lighter feathers). Suppose two Dd birds mate. What percentages of DD, Dd, and dd offspring would you predict? Use the Punnett square at right to help determin...

Evolutionary Analysis Exam 1 question and answers graded A+ 2023 Hardy-Weinberg equilibrium principle states - correct answer allele frequencies in a population will not change from generation to generation; if allele frequencies are p and q, genotype frequencies will be p^2, 2pq, q^2 mechanisms of evolution - correct answer drift, selection, migration, mutation population genetics - correct answer integrates natural selection with Mendelian genetics evolution is ______ in a population...

Natural Selection the process that results in adaptation of a population to the biotic and abiotic environments. Polygenic controlled by more than one pair of alleles located at different gene loci Directional Selection occurs when an extreme phenotype is favored and the distribution curve shifts in that direction. Example: resistance to antibiotics and pesticides Stabilizing Selection Occurs when an intermediate phenotype is favored. Individuals near the average are fav...

BIO CHAPTER 14 Exam Questions With 100% Correct Answers. Bottleneck effect - answerA type of genetic drift that occurs when a population is suddenly reduced to a small number of individuals, and as a result alleles are lost from the population. founder effect - answerA type of genetic drift in which a small number of individuals leaves one population and establishes a new population, resulting in lower genetic diversity than in the original population. genetic drift - answerRandom changes...
