Mechanisms of Evolution

Front

What is genetic recombination?

Back

A mechanism of evolution where chromosomes are crossed over during prophase I of meiosis, creating new alleles.

Front

What is a gene pool?

Back

The total set of different alleles in a population.

Front

What is the founder effect?

Back

A phenomenon where a small group from a population starts a new population, leading to reduced genetic diversity.

Front

What is mutation in the context of evolution?

Back

A change in the DNA sequence that can lead to new traits in an organism.

Front

What causes genetic drift?

Back

Random chance events that change the allele frequency in a population.

Front

What is natural selection?

Back

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

Front

What is gene flow?

Back

The transfer of alleles or genes from one population to another.

Front

How does genetic drift differ from natural selection?

Back

Genetic drift is due to random chance, while natural selection is based on the fitness of traits.

Front

What is the significance of allele frequency?

Back

It indicates how common an allele is in a population, influencing evolution.

Front

What role does sexual reproduction play in evolution?

Back

It increases genetic variation through recombination of alleles.
