Population Correct Answer: group of organisms of the same species living in the same place Population Genetics Correct Answer: study of properties of genes in populations Allelic Frequency Cor... rect Answer: Sum of allele/100 p Correct Answer: individuals homozygous first allele 2pq Correct Answer: individuals heterozygous for alleles q Correct Answer: individuals homozygous for the second allele Hardy-Weinberg Principle Correct Answer: Original proportions of genotypes in a population will remain constant from generation to generation -sexual reproduction (meisosis and fertilization) alone will not change allelic (genotypic) proportions Hardy Weinberg Principle 5 Assumptions Correct Answer: -the population size is large -random mating is occuring -No mutations take place -No genes are input from other sources (no immigration) -No selection occurs Polymorphism Correct Answer: a locus with more variation than can be explained by mutation Five Agents of Population Change Correct Answer: 1. Mutation 2. Gene Flow 3. Nonrandom Mating 4. Genetic Drift 5. Selection Mutation Correct Answer: rates are generally so low that they have little effect on Hardy-Weinberg proportions of common alleles *ultimate source of genetic variation Gene Flow Correct Answer: Movement of alleles from one population to another -tend to homogenize allele frequencies Nonrandom Mating Correct [Show More]
