Suppose a population of organisms is in Hardy–Weinberg equilibrium with respect to a gene that has two alleles, Y and y. The
YY genotype has a frequency of 0.11, the Yy genotype has a frequency of 0.44, and the y genotype has a frequency of 0.45.
Calculate the frequency of each allele to two decimal places.
Y allele frequency:

- The Hardy-Weinberg principle states that allele and genotype frequencies remain constant from one generation to the next, as long as specific conditions are met. Choose Yes or No for the conditions that must be met from the providied statement below. 1. Mutations are exponentially occuring 2. All member of the population breed 3. Everyone produces the same number of offspring 4. The population is infinitely large 5. There is no migration in or out of the population 6. No net mutations are occuring 7. Natural selection of beneficial traits is occuring 8. Natural selection is not occuring 9. All mating is completely random 10.
