Questions and Answers
Why are gene frequencies subject to sampling variation between successive generations?
Why are gene frequencies subject to sampling variation between successive generations?
- Because the gene frequencies are constant in each generation
- Because the population size directly affects the sampling variation (correct)
- Because the gene frequencies change with each generation
- Because the number of parents determines the gene frequencies
What is the significance of a 'large population' in terms of gene frequencies?
What is the significance of a 'large population' in terms of gene frequencies?
- It reduces the genetic diversity within the population
- It accelerates the transfer of genes from one generation to the next
- It minimizes the impact of sampling variation on gene frequencies (correct)
- It increases the likelihood of genetic mutations
How does the number of adult individuals in a population affect gene frequencies?
How does the number of adult individuals in a population affect gene frequencies?
- It has no effect on gene frequencies
- It influences the magnitude of sampling variation in gene frequencies (correct)
- It causes the gene frequencies to remain constant over generations
- It directly determines the rate of gene mutations
