Genetic Drift Vocab Test

n - is the differential survival and reproduction of some individuals over others due to differences in their traits.

• Adaptation

• Artificial Selection

• Evolution

• Natural Selection

- traits that exist in a present organism, but did not exist in the organism's ancestors.

• Ancestral Traits

• Allele

• Derived Traits

• Biogeography

traits that exist in a present organism and also in the organisms ancestors, for example teeth or nails

• Fitness

• Derived Traits

• Adaption

• Ancestral Traits

- the relative frequency of an allele (alternative forms of a gene) at a particular locus in a population.

• Analogous

• Allele Frequency

• Vestigial

• Genetic Drift

- the intentional breeding of plants or animals for their desirable traits, often called selective breeding.

• Genetic Drift

• Artificial Selection

• Biogeography

• Natural Selection

A structure in an organism that has lost all or most of its original function in the course of evolution, such as human appendixes.

• Genetic Bottleneck

• Gene Flow

• Evolution

• Vestigial

a trait shaped by natural selection that increases and organisms chance of survival and reproductive success. For example camouflage or mimicry.

• Genetic Drift

• Adaptation

• Disruptive Selection

• Divergent Evolution

– a measure of the relative contribution a trait makes to the next generation, often expressed as the number of viable offspring an organism produces in the next generation

• Stabilizing Selection

• Directional Selection

• Fitness

• Hardy-Weinberg Principle

the study of the distribution of species

• Biogeography

• Vestigial

• Allele

• Founder Effect

- changes in the frequencies of alleles within a population of organisms.

• Evolution

• Homology

• Adaptation

• Allopatric Speciation
