Module 11 Flashcards
is a random process that can cause the gene pool of a population to change randomly from one generation to the next overtime
Genetic Drift
is the process in which one species splits to form two or more species that are reproductively isolated from each other
Speciation
is the sum of all genetic information carried by all the individuals in a population.
Gene Pool
For mechanisms can change the composition of a populations gene pool
Mutation. Gene Flow Genetic Drift Natural Selection
is the movement of genes from one population to another
Gene Flow
Can occur when population of a single species become separated or geographically isolated from one another
Geographic Isolation
The formation of new species from geographically isolated populations
Allopatric speciation
Are the ultimate source of all genetic variations and are the result of random changes in DNA sequence
Mutations
is the process by which only individuals with certain inherited characteristics are allowed to breed
Artificial Selection
The process by which a population gains one or more alleles that enable it to survive better than other populations
Natural Selection
The process by which a population as a whole becomes better matched to its habitat over successive generations is known as
Adaptation
Are genetic characteristsc that enable the individuals to function well, and therefore survive and reproduce better in a competitive environment
Adaptive Traits
The formation of new species in the absence of geographic isolation is called
Sympatric Speciation
