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? Only if the population is in Hardy-Weinberg equilibrium Only if the population is NOT in Hardy-Weinberg equilibrium Always: It doesn't matter whether or not the population is in Hardy-Weinberg equilibrium

What is one assumption of the Hardy-Weinberg law that does not hold true for all populations?
Eye color in a species of fruitfly is determined by a single locus with two alleles: E and e. EE individuals have red eyes, Ee have pink eyes, and ee individuals have brown eyes. In a lab population that is in Hardy–Weinberg equilibrium, we count 27 flies with brown eyes out of 164. How many flies can you expect to have red eyes? Round your answer to the closest integer value.
Consider the B locus which has two alleles in a population: B and b. Researchers examined the genotypes several individuals for this locus and obtained the following numbers B/B: 320individuals B/b: 60individuals b/b: 12individuals If the B locus is at Hardy-Weinberg equilibrium, what would the expected number of individuals with the Bb genotype? Round your answer to the closest full number.

The next several questions refer to the data given in this problem. You sample a population of leafhoppers and genotype 250 individuals at a polymorphic locus with two alleles. You obtain the following numbers: AA = 68 individuals Aa = 54 individuals aa = 128 individuals What is the frequency of the A allele? (You may round your answer to 2 decimal places) What is the expected number of individuals with the AA genotype if the population is in Hardy Weinberg equilibrium? (You may round your answer to the nearest whole number) What is the expected number of individuals with the Aa genotype if the population is in Hardy-Weinberg equilibrium? (you may round your answer to the nearest whole number)
A population of 40 asters segregating at two loci with two alleles each (A/T and G/C) has 8 individuals with the AAGGgenotype. The allele frequencies of A and G are 0.5 and 0.5 in the population. What is the coefficient of gametic disequilibrium, D? What is the value of Lewontin’s D’? (that is “D prime”)
in the Hardy-Weinberg equation, what do the terms p2, q2, and 2pq represent, in terms of the genetic structure of a population?
In a population with two alleles at the R locus (R and r), the frequency of the genotype rr is 0.24. Assuming that the R locus is at Hardy-Weinberg equilibrium in this population, what is the frequency of heterozygotes (Rr)? Round and report your answer to the second decimal place (0.00). Your Answer:
The two-tailed p-value associated with this test is 0.860. Should the null hypothesis be rejected? Is there sufficient evidence to suggest that there is a statistically significant difference between the two means in question? If we now wanted to know whether there was a difference in weight between those with a low NYHA class (1 and 2) and those with a high NYHA class (3 and 4), what p-value would you report?
Pretend that you are comparing the actual genotype distribution for a population with the distribution of genotypes predicted by the Hardy-Weinberg theorem. So your hypothesis is that the population is in Hardy-Weinberg equilibrium (i.e. that actual population data fit the Hardy-Weinberg expectations). If you carry out a chisquare goodness of fit test and calculate a total chisquare value of 0.03 with 1 degree of freedom (see table), what does this mean? (select all true statements)a) The data do NOT fit the hypothesized distribution.b) The data do fit the hypothesized distribution well enough, so we accept the hypothesis at this time (i.e. we cannot reject the hypothesis). c) The probability that the data came from a population in Hardy-Weinberg equilibrium is too small, so we reject the hypothesis.d) The probability that the data came from a population in Hardy-Weinberg equilibrium is too big, so we reject the hypothesis.e) The data support Hardy-Weinberg expectations – there is no…
