What is behavioral isolation?

Back

Behavioral isolation occurs when different species develop distinct mating behaviors or calls, preventing them from interbreeding.

Front

What is temporal isolation?

Back

Temporal isolation is a form of reproductive isolation where species breed at different times, preventing mating.

Front

Give an example of temporal isolation.

Back

An example of temporal isolation is when one plant species blooms in June while another blooms in September.

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 the founder effect?

Back

The founder effect occurs when a small group of individuals establishes a new population, leading to different allele frequencies compared to the original population.

Front

What can prevent evolution from occurring?

Back

Non-random mating can prevent evolution by maintaining certain allele frequencies in a population.

Front

How does a small gene pool affect a population?

Back

A small gene pool can lead to reduced genetic diversity, making a population more vulnerable to extinction.

Front

What is geographic isolation?

Back

Geographic isolation occurs when physical barriers, such as mountains or rivers, separate populations, preventing interbreeding.

Front

What is the significance of allele frequency?

Back

Allele frequency refers to how often a particular allele appears in a population, influencing genetic diversity and evolution.

Front

What role do mutations play in evolution?

Back

Mutations introduce new genetic variations, which can lead to evolutionary changes if they provide a survival advantage.
