Which of the following is NOT an assumption made when using the Hardy-Weinberg formula?

Which of the following formulas can be used to calculate heterozygote frequency in a population?

In a random mating population of Drosophila, 5% of the flies have black bodies (encoded by recessive b) and 95% have brown bodies (encoded by B). Assuming Hardy-Weinberg equilibrium what is the allele frequency of B in the population?

In a random mating population of Drosophila, 5% of the flies have black bodies (encoded by recessive b) and 95% have brown bodies (encoded by B). Assuming Hardy-Weinberg equilibrium what is the genotypic frequency of BB in the population?

In a population where only the total number of individuals with the dominant phenotype is known, how can you calculate the percentage of carriers and homozygous recessives?

Consider a population in which the frequency of allele A is p=0.7 and the frequency of allele a is q=0.3 and where the alleles are codominant. What will be the allele frequencies after one generation if the following occurs?

wAA=0.8, wAa=1, waa=0.8
