10 Gene Flow & Mutation_Student

Gene Flow

The movement of alleles from one population to another.

Mutation

A change in the nucleotide sequence of an organism's DNA.

Dispersal

A one-way movement by an individual from the area where it was born to the area where it breeds.

Biased Gene Flow

Gene flow that is influenced by human activities, affecting the fitness of wild populations.

Point Mutation

A change in a single nucleotide that may lead to a different protein.

Lateral Gene Transfer

The transfer of genes from one species to another or the incorporation of DNA from the environment.

Transformation

A process by which bacteria take up new alleles from their environment.

Conjugation

The transfer of new alleles from one bacterium to another through direct contact.

Transduction

The process by which bacteriophages transfer genetic material from one bacterium to another.

Selection

The process wherein certain traits increase in frequency due to individuals with those traits being more fit for survival.

Genetic Variation

The diversity in gene frequencies among individuals within a population.

Allele Frequencies

The relative frequency of an allele at a genetic locus in a population.

Captive-bred

Individuals that are bred in controlled environments, usually for conservation purposes.

Ecological Vision

A strategic plan for maintaining or enhancing ecosystem health and connectivity.

Natural Selection

The process by which organisms better adapted to their environment tend to survive and produce more offspring.

Environmental Change

Changes in the environment that can affect the survival and reproduction of species, caused by both natural factors and human activities.
