M3 - Evolution and Gene Frequency Flashcards
The collection of ALL the alleles for all the traits and genetic variations of a certain population that is necessary for evolution
Gene pool
A group of organisms of the same species with a common set of genes living in a particular area for a given time where genetic changes are passed on to every generation.
Population
Some genes may have a little to none at all variation among the population
Gene pool
A biological field dealing with the genetic makeup of populations and the factors changing its composition
Population genetics
Abstract Mathematical models are used to analyze and predict genetic patterns and variations
Population Genetics
Allele frequencies remain constant (or at equilibrium) over generations in the absence of distressing factors
Hardy-Weinberg Theorem
introduction of new alleles
Mutations
occurrence of beneficial or detrimental alleles
Natural Selection and Nonrandom Mating
the random fluctuations in the chances of allele frequencies, especially in small populations
Genetic Drift
inbreeding of two populations to produce another population
Gene flow
basic unit of classification
Species
Group of populations that can interbreed and as a consequence genes either actually or potentially exchanged, referred to as biological species concept
Species
Group of populations that independently evolved, this on the other hand is phylogenetic species concept
Species
formation of new species
Speciation
Speciation happens if there are geographic barriers between subpopulations
Allopatric Speciation
