What are the four principles of natural selection?
1. overproduction of offspring
2. variation
3. Adaptation
4. Descent with modification
The random loss of alleles in a population is called?
Genetic drift
How are food chains and food webs different?

Certain breeds of chickens can be lack feathered, white feathered, or checkered feathered, this is an example of what complex inheritance pattern?
Codominance
Blood types A, B, AB, and O are the result of _________ inheritance
Multiple alleles
These three things affect microevolution
1. Genetic drift
2. Genetic flow
3. Sexual selection
These are five evidences of evolution
1. morphology
2. Biogeography
3. Biochemistry
4. Embryology
5. Paleontology
Describe a detrivore
Organism that breaks down the dead
Tallness (T) is dominant to dwarfness (t), while red (R) flower color is dominant to white (r). The heterozygous condition results in pink (Rr) flower color. A dwarf, homozygous red snapdragon is crossed with a plant homozygous for tallness and white flowers. What are the genotypes and phenotypes of the F1 individuals?
TtRr tall and pink
Skin color is controlled by 6 different genes, this is what complex inheritance pattern?
Polygenic trait
What is the correct hierarchy of classification going from broadest to most specific?
Domain, kingdom, phylum, class, order, family, genius, species
Evolution will not occur if these five things are in play
1. population is too large
2. random mating occurs
3. no migration
4. no mutations
5. no natural selection
NAme two biotic limiting factors and two abiotic limiting factors to an ecosystem.
biotic: food, mating, etc
abiotic: water, oxygen, biogeography etc
