AP Biology- Hardy Weinberg
What are the five agents of evolutionary change? - Answer mutation, gene flow, non
random mating, genetic drift, selection
How does mutation cause evolution? - Answer results in variation in a population
How does gene flow cause evolution? - Answer interbreeding between different
populations brings new alleles
How does non-random mating cause evolution? - Answer there would be no selection
or change to the population
How does genetic drift cause evolution? - Answer change in allele frequency in a
population
How does selection cause evolution? - Answer they would all be equally fit and never
change
What is a population? - Answer localized group that can interbreed
What is a gene pool? - Answer collection of all alleles in a population
What is the difference between alleles and genes? - Answer alleles are all the genes
What is allele frequency? - Answer how common an allele is in a population
What is evolution? - Answer change in allele frequency
How could a population never evolve? - Answer remove all agents of evolution (no
mutation, gene flow, non random mating, genetic drift, selection)
What is the Hardy Weinberg equation used for? - Answer to measure if forces are
acting on a population
Which formula do you use to count alleles in a population? - Answer p+q=1
Which formula do you use to count individuals in a population? - Answer p²+2pq+q²=1
What does the p² represent in the equation? - Answer homozygous dominant
What does the q² represent in the equation? - Answer homozygous recessive
What does the 2pq represent in the equation? - Answer heterozygous
Explain sickle cell anemia. - Answer a mutation in the hemoglobin that prevent a blood
cell from having enough oxygen
