The Five Fingers of Evolution Flashcard Honors

Front

What is evolution?

Back

Evolution is the change in the frequency of genes in a population over time, leading to the development of new species.

Front

What happens if the frequency of a gene in the gene pool changes?

Back

It indicates that evolution has occurred.

Front

What is a gene mutation?

Back

A gene mutation is a change in the DNA sequence that can lead to new traits, such as a new hair color.

Front

How does a gene mutation affect the gene pool?

Back

It changes the frequency of genes in the gene pool.

Front

What is genetic variation?

Back

Genetic variation refers to the diversity in gene frequencies within a population, which is essential for evolution.

Front

What role does sexual reproduction play in evolution?

Back

Sexual reproduction reshuffles genes, leading to genetic variation in the next generation.

Front

Why is red hair advantageous in northern climates?

Back

Red hair allows for more vitamin D synthesis, which is beneficial in areas with less sunlight.

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 gene flow?

Back

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

Front

What does the little finger represent in the Five Fingers of Evolution?

Back

The little finger represents small population size, which can lead to genetic drift.
