Consider a population in which the D locus has two alleles, D and d, with f(D) = 0.6 and f(d) = 0.4. What are the genotypic frequencies expected under Hardy-Weinberg equilibrium?

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”)

Approximately 1% of the magpies (Pica pica) in a hypothetical populations are albino. Assume that the albino phenotype is due to a recessive allele and that this population is in HardyWeinberg proportions at this locus.   (a)  What is the estimated frequency of the albino allele in this population?  (b) What is the probability that the first progeny born to a mating between an albino and a normal magpie from this population will be albino? (Hint: what is the probability that the normal magpie is heterozygous, given the allele frequencies in this population?)

In a certain population in the US, the frequency of CCR5-Δ32 homozygous individuals is 1%. Assuming genetic equilibrium, what is the frequency of heterozygotes in this population?

In a gorilla population in Zaire we consider a single gene locus with two alleles G and g, with G dominant to g. The frequency of the allele g is 0.01. Assuming Hardy- Weinberg proportions, the frequency of the genotype Gg is:

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…

Consider an autosomal locus with alleles A and a. If the the allele frequencies are as follows Freq(A) = 0.4, Freq(a) = 0.6. , then what is the predicted frequency of heterozygous Aa individuals, assuming the population is in Hardy-Weinberg equilibrium? Freq(Aa) = ? Enter a number between 0 and 1, inclusive, for example 0.33

Tail length in a population of peacocks has a phenotypic variance of 2.56cm^2 and an enviromental variance of 1.14cm^2. What is the broad sense heritability (H2)?
