Genetic Diversity and Population Dynamics

Front

What is a population?

Back

A group of the same species.

Front

What does the Founder Effect refer to in genetic drift?

Back

It occurs when a small group of individuals establishes a new population, leading to reduced genetic diversity.

Front

What is gene flow?

Back

The transfer of genetic material between populations, often through migration.

Front

What is the Bottleneck Effect?

Back

A sharp reduction in population size due to environmental events, leading to a loss of genetic diversity.

Front

What are homologous structures?

Back

Structures in different species that share a common ancestor.

Front

What is genetic drift?

Back

Random changes in allele frequencies in a population, often having a more significant effect in small populations.

Front

What is the difference between artificial selection and natural selection?

Back

Artificial selection is human-directed breeding for specific traits, while natural selection is the process where organisms better adapted to their environment tend to survive and reproduce.

Front

What is non-random mating?

Back

Mating that occurs based on specific traits or preferences, leading to certain alleles being passed on more frequently.

Front

What is coevolution?

Back

The process where two or more species influence each other's evolution.

Front

What is a gene pool?

Back

The total collection of genes and alleles in a population.
