Population Genetics
Phenotypic and genotypic variation exists among populations
Hardy Weinberg Equilibrum
selection
gene flow
random mating
Diversity and its Recognition
diversity increases specialization
different species to have differenct or the same niches in an environment
Population Regulation
competition due to limited food, water, and shelter
predation
density dependent regulatory factors
regulates the size of the population
disease
Mutation and Genetic Drift
Mutations are a random change in the genetic code
The ultimate source of genetic variation
Genetic drift results from random changes in gene frequency from one generation to another
formation of new species
Speciation
formation of new and different species
geographic isolation
repoductive isolation
new species form and some species may disappear
Species Interaction
several different relationships among species
mutualism
commensalism
parasitism
the relationships may or may not be beneficial for one species and even have negative consequences
predation
competition
