Bio 311D Concept Map Simon Yu
Species Interaction
several different relationships among species
competition
parasitism
the relationships may or may not be beneficial for one species and even have negative consequences
commensalism
mutualism
Speciation
formation of new and different species
repoductive isolation
new species form and some species may disappear
geographic isolation
Mutation and Genetic Drift
Genetic drift results from random changes in gene frequency from one generation to another
formation of new species
Mutations are a random change in the genetic code
The ultimate source of genetic variation
Population Regulation
disease
predation
density dependent regulatory factors
regulates the size of the population
competition due to limited food, water, and shelter
Diversity and its Recognition
diversity increases specialization
different species to have differenct or the same niches in an environment
Population Genetics
Hardy Weinberg Equilibrum
random mating
gene flow
selection
Phenotypic and genotypic variation exists among populations
