6.1 Hardy-Weinberg Principle & Assumptions — Test 1
Q1. Gene flow is:✓ Movement of alleles from one population to another
Q2. The Hardy-Weinberg principle states that:✓ Allele and genotype frequencies stay constant in the absence of evolutionary agents
Q3. The Hardy-Weinberg equation (p+q)² = p² + 2pq + q² = 1 is used in:✓ Population genetics
Q4. In the Hardy-Weinberg equation, p and q stand for:✓ Frequencies of the two alleles in the population
Q5. In the Hardy-Weinberg equation, the term q² refers to the frequency of:✓ The homozygous recessive genotype
Q6. In p² + 2pq + q² = 1, which term indicates the frequency of heterozygotes?✓ 2pq
Q7. Which set of genotype frequencies (AA, Aa, aa) is consistent with Hardy-Weinberg equilibrium?✓ 0.25, 0.50, 0.25
Q8. Which assumption is required for Hardy-Weinberg equilibrium?✓ Random mating
Q9. Hardy-Weinberg equilibrium can be disturbed by:✓ All of these

Q11. Which factor does NOT, by itself, disturb Hardy-Weinberg equilibrium?✓ Random mating
Q12. A randomly interbreeding local population is called a:✓ Deme
Q13. A randomly interbreeding population is described as:✓ Panmictic
Q14. A group of potentially interbreeding individuals in a given location is referred to as a:✓ Population
Q15. The gene pool of a population refers to the:✓ Total of all alleles of all genes in all individuals of the population
Q16. Which model first showed how genetic variation is preserved under Mendelian inheritance?✓ Hardy-Weinberg model
Q17. Which combination of conditions best maintains the stability of a gene pool?✓ Large population, no net mutation, no selection, random mating
Q18. Hardy-Weinberg equilibrium assumes the population size is:✓ Effectively infinite (very large)
