You are given the frequencies of all three genotypes (AA, Aa, aa) in a population, and all three are non-zero. Under what conditions can you determine allele frequencies? a) Only if the population is in Hardy-Weinberg equilibrium b) Only if the population is NOT in Hardy-Weinberg equilibrium c) Always: It doesn't matter whether or not the population is in Hardy-Weinberg equilibrium

A hypothetical population of 10,000 humans has 6848 individuals with the blood type AA, 2846 individuals with blood type AB, and 306 individuals with the blood type BB. What is the frequency of each genotype in this population? What is the frequency of the A allele? What is the frequency of the B allele? If the next generation contained 25,000 individuals, how many individuals would have blood type BB, assuming the population is in Hardy-Weinberg equilibrium?
If the frequency of allele b is 0.3 for a population in Hardy-Weinberg equilibrium, what percentage of that population would you expect to be BB, Bb, and bb?
10,000 individuals are sampled from a population and are found to display one of three blood types: AA with 6800 individuals, AB with 2800 individuals and type BB with 400 individuals. a) If the next generation contains 25,000 individuals, how many would have blood type BB, assuming the population is in Hardy-Weinberg Equilibrium?
A hypothetical population of 10,000 humans has 6840 individuals with the blood type AA, 2860 individuals with blood type AB and 300 individuals with the blood type BB. If the next generation contained 25,000 individuals, how may individuals would have BB blood type, assuming the population is in Hardy-Weinberg equilibrium? Express as a whole number.
You are given the frequencies of both alleles (A and a) in a population, and both are non-zero. Under what conditions can you determine genotype frequencies? a) Only if the population is in Hardy-Weinberg equilibrium b) Only if the population is NOT in Hardy-Weinberg equilibrium c) Always: It doesn't matter whether or not the population is in Hardy-Weinberg equilibrium
If a population were to remain in Hardy Weinberg Equilibrium, which of the following is correct? If a population were to remain in Hardy Weinberg Equilibrium, which of the following is correct? The population can still grow, but the allele frequencies will remain constant in each generation The population can still grow, but the allele frequencies may change with each generation Since it is at equilibrium, the population cannot grow
you (should have) learned that selection alone cannot purge a population of the very last copy of a deleterious allele. If selection is unable to do so, which of the remaining mechanisms (of the five Hardy-Weinberg) assumptions is MOST LIKELY to do so? Justify your answer. That is, why is the mechanism you picked the most likely to get rid of that last copy of a harmful allele?
A sample of 100 individuals from a population that is dimorphic at the A locus has genotype counts as follows. AA: 30 Aa: 60 aa: 10 a) What are the allele frequencies in the population? b) What are the expected genotype frequencies, if the population were at HardyWeinberg equilibrium? c) Is the proportion of heterozygotes lower or higher than expected at Hardy-Weinberg equilibrium? What deviations from the assumptions of the model would best explain the observed difference?
If a population is in Hardy-Weinberg Equilibrium, where the dominant allele frequency is 0.2. Which of the following is true about the recessive allele frequency? Select the formula that you would use to find it. q = 1- 2pq q = p/2 q=1-p q = 0.05 then tell us if the statement "Populations in nature are ALWAYS in Hardy-Weinberg Equilibrium" is TRUE or FALSE
10,000 individuals are sampled from a population and are found to display one of three blood types: AA with 6800 individuals, AB with 2800 individuals and type BB with 400 individuals. a) What is the frequency of each genotype in the population? b) What is the frequency of the A allele? c) What is the frequency of the B allele? d) If the next generation contains 25,000 individuals, how many would have blood type BB, assuming the population is in Hardy-Weinberg Equilibrium?
When we find a population whose allele frequencies are not in Hardy–Weinberg equilibrium, what can and can’t we conclude about that population?
In a dense forest, a population of squirrels has been observed for their fur color. The fur color is determined by a single gene with two alleles: B (black) and b (brown). In a sample of 100 squirrels, you observed 30 black (BB), 50 black-brown (Bb), and 20 brown (bb) individuals. Determine if this population is in Hardy-Weinberg equilibrium and show your work.
