- 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. Offspring are able to migrate out of the populationA survey of a butterfly population showed that most individuals have blue wing spots. On occasion, some rare yellow-spotted individuals can be found as well. Further genetic studies showed that the colors are controlled by a single gene, with C dominant over c. Also, out of 300 samples, only 27 are yellow and the rest blue.

There are initially 60 DD, 60 Dd, and 60 dd birds in a population, and the selection coefficient against light - coloured birds is 0.4. If 80% of each dark - coloured genotype survives (48 DD and 48 Dd), how many light-coloured birds would you expect to see in the next generation?Consider a gene with two alleles, C and M.
