Said that populations have the potential to grow exponentially
Developed nearly identical theory of natural selection around the same time as Darwin
Cuvier’s belief that periodic natural disasters wiped out large groups of organisms that were replaced by organisms from another region
Believed that organisms were fixed and not evolving and could be placed on a ladder of increasing complexity
What is The Origin of Species by Means of Natural Selection?
Must already exist in a population for natural selection to occur
Species concept that defines a species based on physical characteristics
Type of speciation that occurs when a population is geographically separated
One species of flower blooms in the spring but another blooms in the fall
Hybrids between two species are unable to mate and produce offspring
Represents the proportion of dominant alleles in a population in the HWE
Frequency of dominant allele in the population where 16% show the recessive phenotype
What is 0.6?q2 = 0.16q = 0.4p + q = 1p = 1- q = 1- 0.4 = 0.6
Frequency of heterozygotes in a population where 64% show the dominant phenotype
What is 0.48 (or 48%)? p2 + 2pq + q2 = 1 p2 + 2pq = 0.64q2 = 1- 0.64 = 0.36q = 0.6, so p = .42pq = 2 * 0.6 * 0.4 = .48
Term for when a small population colonizes a new habitat separating itself from the parent population
Genetic exchange caused by migration of organism or gametes into or out of a population
