Unit 11 Review

Front

What is asexual reproduction?

Back

A form of reproduction where a single organism produces offspring that are genetically identical to itself.

Front

What is a disadvantage of asexual reproduction?

Back

Results in low genetic variation of the species.

Front

What is sexual reproduction?

Back

A form of reproduction that involves the combination of genetic material from two parents, resulting in offspring with genetic variation.

Front

What are the advantages of sexual reproduction?

Back

Increases genetic variation, which can enhance survival and adaptability of a species.

Front

What is natural selection?

Back

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

Front

How does natural selection affect a population over time?

Back

Traits that help an organism survive and reproduce become more common in future generations.

Front

What is artificial selection?

Back

The intentional breeding of organisms with desirable traits by humans.

Front

What is genetic variation?

Back

The diversity in gene frequencies among individuals within a population.

Front

Why do wild sunflowers have more petal color variation than farm-grown sunflowers?

Back

Wild sunflowers experience natural selection, while farm-grown sunflowers are often bred for specific traits, like bright yellow color.

Front

What is the role of competition in natural selection?

Back

Competition for resources, mates, and survival leads to the selection of the fittest individuals.
