Agenetic study conducted over two generations found that the frequencies of genotypes in the first generation were aa: 0.36, aa: 0.48, aa: 0.16. in the second generation, genotype frequencies remained the same. according to hardy–weinberg equilibrium, what can we assume?

For the genotypic frequency to remain the same over generations, then according to Hardy-Weinburg, the following five assumptions are presumed;

1.       That the population is large enough for sampling hence there is no genetic drift

2.       Natural selection is not acting on the population

3.       No gene flow between the population being studied with another population occurred either through migration etcetera

4.        No/negligible mutations occurred

5.       Mating between individuals of the population is occurring randomly

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good

explanation:

he forelimbs below belong to four species that descended in a direct line from the ancestral mammal shown above. of the four descendants shown, which species most likely appeared earliest in evolutionary history?
