|
Conceptually, all of the alleles of every gene in a population |
GENE POOL |
|
|
A group of individuals of the same species that occupy the same region and can interbreed with one another. |
POPULATION |
|
|
Members are more likely to breed among themselves than with other of the general population. |
LOCAL POPULATIONS, or DEMES |
|
|
A gene that exists in two or more alleles in a population. |
POLYMORPHIC |
|
|
A gene that exists predominantly as a single allele in a population. |
MONOMORPHIC |
|
|
Smallest type of genetic change that can occur within a given gene, also the most common. |
SINGLE-NUCLEOTIDE POLYMORPHISM (SNP) |
|
|
# of copies of a specific allele in a population -------------------------------------------------------------- = Total number of all types of alleles for that gene in a population |
Allele Frequency |
|
|
Number of individuals with a particular genotype in a population -------------------------------------------------------- = Total number of individuals in a population |
Genotype frequency |
|
|
A simple mathematical expression that predicts stability of allele and genotype frequencies from one generation to the next |
HARDY - WEINBERG EQUILIBRIUM |
|
|
p^2 + 2pq + q^2 = 1 |
HARDY - WEINBERG EQUATION |
|
|
High X-square ... allele and genotype frequencies are evolving. |
DISEQUILIBRIUM |
|
|
Environmental conditions favor reproduction of individuals that adapt more quickly. |
NATURAL SELECTION -
proposed indepedently by Darwin and Wallace in the 1850s |
|
|
The relative likelihood that one genotype will contribute more to the gene pool of the next generation. |
DARWINIAN FITNESS |
