Reproductive Isolation

Gene Frequency in a Populations

A genetic gene pool is the set of all genes, or genetic information, in any population, that is normally in one species

A genetic drift is the change in the frequency of a gene allele in a population due to random sampling of organisms.

The bottleneck effect is Genetic drift can cause big losses of genetic variation for small populations

Non-random mating is when organism with similar genotypes and phenotypes produce offsprings.

Natural Selection is the process of organsims adapting to their enviroment to be most likely to survive and produce offspring.

Mutation is changing the structure of genes resulting in varient froms of the species.

Genetic drift is the variation in the relative frequency of the different types of genotypes in a small population, then some of the genes disappear through reproduction.

Gene flow is the alteration of the frequencies of alleles of one gene in a population.

Geographic isolation is the same thing as allopatric specaiton. It is when species become sperated by a physicail barrior such as water of mountains.

Behavioral Isolation is when same species can identify eachother as mates.

Symaptric speciation is when new species evolve through a common ancestor.

Allopatric speciation is speciation by geograpic isolation. Species because seperated by a physcial barrior.

Temporal isolation is when species will mate or flowers at different times of the day or different seasons.

Hybridization is the process of combining two complementary single-stranded DNA or RNA molecules and allowing them to form a single double-stranded molecule through base pairing.
