The Founder Effect
The founder effect is when a few individuals of a species form a new population. The gene pool composition, therefore, is not reflective of the gene pool of the original population. Think of this as a small number of people starting their own colony.
This is an example of the Founder effect because Polydactyly is a dominant trait. And in a large population, it will be rare finding a person with a 6th digit. In a smaller population, however, polydactyly has a higher frequency of this allele, because the smaller the population, the higher the sensitivity for inbreeding and lower genetic variation. So, polydactyly (dominant allele) + Increase inbreeding= Higher polydactyly allele frequency.

If you know the phenotypes of all organisms in a population you can calculate the allelic frequency of the population?
Yes, use the Hardy-Weinburg equilibrium equation.
The theory of modern synthesis states that evolution involves changes in a population's?
population
Which event describes a change where evolution has happened?
An allele frequency changes in a population.
Does natural selection cause a change in the gene frequencies of the population over time?
Recessive genes are replaced by dominant genes over time and unfavorable genes die out.
Does evolution occur at the level of the organisms?
No, organisms die.Evolution is the change in allele frequency over time in a population of organisms.

Genetic Drift
What is a small founding population of a few hundred Europeans in North America had an unusually high frequency of an allele that causes polydactyly (six fingers) an example of?
Founder Effect
What question did Hardy and Weinberg want to answer?
To determine how allele frequency changes
What happens when a population is in hardy wienberg equilibrium?
Allele frequency is stable The phenotype frequency does not change.

What is a part of microevolution?
One example of microevolution is genetic variation within a population. This occurs because of the accumulation of small changes in the frequency of alleles (alternative forms of a gene) over generations.
