Why do traits differ between the offspring from the same parents?

Back

Different offspring can inherit different copies of alleles from the parents.

What is the most likely explanation for the change in a population of ladybugs over 15 years?

Front

What is the process by which populations of organisms with variations that help them survive in their environments live longer, compete better, and reproduce more than those that do not have the variations?

Back

natural selection

Back

An allele is a variant form of a gene that can result in different traits.

Front

Migration is the seasonal movement of animals from one region to another for feeding or breeding.

Front

What is a structural adaptation?

Back

A structural adaptation is a physical feature of an organism that enhances its survival.

Front

What is a physiological adaptation?

Back

A physiological adaptation is a functional change in an organism's body that helps it survive in its environment.

Front

What is the role of chloroplasts in plant cells?
