Study Notes
- Phenotypic differences are due to genes that code for traits.
- Natural selection favors advantageous traits within a population.
- Mutations and crossing over/recombination can result in genetic variation.
- Allele frequency is the proportion of one allele in the gene pool.
- The Hardy-Weinberg equation is used to determine equilibrium in populations.
- The equilibrium is disrupted by mutations, small population size, natural selection, gene flow, and non-random mating.
- Scientists use the Hardy-Weinberg model to compare real populations.
- The beak length of penguins follows a normal distribution curve.
- The majority of individuals have a beak length close to the mean.
- Extreme traits are not common in populations.
