Population Genetics starts at 11 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Population Genetics.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
A population has 16% individuals with genotype aa. Assuming Hardy-Weinberg equilibrium, what is the frequency of allele a?
A population has allele frequencies p = 0.3 and q = 0.7. What is the expected frequency of genotype qq?
A population has the following genotype frequencies: 0.25 AA, 0.50 Aa, 0.25 aa. What is the frequency of allele A?
A population of 1000 individuals has 360 AA, 480 Aa, and 160 aa genotypes. What is the frequency of allele a?
A population of 500 individuals has 50 aa individuals. What is the frequency of genotype aa?
Define gene pool.
Define genetic drift.
Describe the effect of assortative mating on genotype frequencies.
Explain the difference between genetic drift and natural selection.
Explain the founder effect.
Explain why mutation alone is usually a weak evolutionary force.
Explain why small populations are more susceptible to genetic drift.
If a population is in Hardy-Weinberg equilibrium, what can be said about the population?
If the frequency of allele A is 0.7 and allele a is 0.3 in a population, what is the expected frequency of heterozygotes (Aa) under Hardy-Weinberg equilibrium?
In a population, p = 0.8 and q = 0.2. What is the expected frequency of heterozygotes?
In a population, the frequency of allele B is 0.6. What is the expected frequency of genotype BB under Hardy-Weinberg equilibrium?
What does the term 'allele frequency' mean?
What is meant by 'fixation' of an allele in a population?
What is the effect of a population bottleneck on genetic diversity?
What is the effect of gene flow between two populations?
