What is gene flow?

Back

Gene flow is the movement of alleles from one population to another, which can change allele frequencies in a population.

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 is genetic drift?

Back

Genetic drift is a random change in allele frequency caused by chance occurrences, often having a more significant effect in small populations.

Front

What is the founder effect?

Back

The founder effect occurs when a small group of individuals migrates to a new area, leading to a new population with a limited genetic diversity.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence of an organism, which can lead to new traits or variations.

Front

How does natural selection lead to evolution?

Back

Natural selection leads to evolution by favoring traits that enhance survival and reproduction, gradually changing the population over generations.

Front

What role does genetic variation play in evolution?

Back

Genetic variation provides the raw material for evolution, allowing populations to adapt to changing environments.

Front

What is the difference between gene flow and genetic drift?

Back

Gene flow involves the movement of alleles between populations, while genetic drift is a random change in allele frequencies within a population.

Front

Can mutations be beneficial?

Back

Yes, mutations can be beneficial, neutral, or harmful, and beneficial mutations can provide an advantage in survival and reproduction.

Front

What is stabilizing selection?

Back

Stabilizing selection is a type of natural selection that favors average phenotypes and reduces variation.
