Mechanisms of Evolution
What is the process where individuals with advantageous traits are more likely to survive and reproduce?
Natural Selection
What provides snapshot of past life
Fossil Evidence
Prezygotic barrier where there are different mating seasons
Temporal Isolation
The equilibrium is named after
G.H. Hardy and W. Weinberg
The four types of selection pressures are
Competition, predation, environmental changes, and human influence
The movement of alleles between populations due to migration of individuals. (It is intentional)
Gene Flow
The study of similarities and differences in physical structures
Comparative Anatomy
Parapatric is
Adjacent but different environments
The equilibrium allows us to
track a population's genotypic and allelic frequencies over time
The three types of natural selection are
Directional selection, stabilizing selection, and disruptive selection
What is the ultimate source of genetic variation?
Mutations
Molecular Biology
Sympatric is
Same location without being separated by a barrier but never interact
It can be used to
calculate if evolutionary forces are acting on a population
Common traits in a population are measured using a
Graph
What are the two effects in genetic drift?
Founder Effect and Bottleneck Effect
The study of early development stages of embryos
Embryology
In hybrid inviability
Offspring do not survive for a long period of time
It is a relationship between
Allele frequencies and genotype frequencies
Darwin's finches are an example of what selection pressure
Competition
Mating that occurs without consideration of traits
Random Mating
Homologous structures are
Similar structures in different species
Barriers cause species to
Not be able to interbreed; separate species
The five condition for the equilibrium are
No mutation, random mating, no natural selection, no gene flow, and a very large population size
Mating where preferences influence selection
Non-random mating
