Genetic Diversity and Population Dynamics

Front

What is genetic diversity?

Back

Genetic diversity refers to the total number of genetic characteristics in the genetic makeup of a species. It is important for the adaptability and survival of species.

Front

What is gene flow?

Back

Gene flow is the transfer of genetic material between populations, which can increase genetic diversity.

Front

What is genetic drift?

Back

Genetic drift is a mechanism of evolution that refers to random changes in the frequency of alleles in a population.

Front

What is artificial selection?

Back

Artificial selection is the process by which humans breed specific plants or animals for desired traits.

Front

What is non-random mating?

Back

Non-random mating occurs when individuals select mates based on specific traits, leading to a change in allele frequencies.

Front

What is the founder effect?

Back

The founder effect is a form of genetic drift that occurs when a small group of individuals establishes a new population.

Front

What is the bottleneck effect?

Back

The bottleneck effect is a sharp reduction in the size of a population due to environmental events, leading to a loss of genetic diversity.

Front

What is antibiotic resistance?

Back

Antibiotic resistance is the ability of bacteria to survive and reproduce despite the presence of antibiotics, demonstrating evolution in action.

Front

What is natural selection?

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What are vestigial structures?

Back

Vestigial structures are anatomical features that have lost most or all of their original function through evolution.
