Front

What is the founder effect?

Back

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

Front

What do the letters B and E represent in a cladogram?

Back

They represent species that are closest in evolution.

Front

What can be inferred from the survival of cockroaches after insecticide spraying?

Back

Individuals with favorable variations survive and reproduce.

Front

Define stabilizing selection.

Back

A type of natural selection that favors intermediate variants by acting against extreme phenotypes.

Front

What is a cladogram?

Back

A diagram that shows the evolutionary relationships among various biological species based on similarities and differences in their physical or genetic characteristics.

Front

Explain the concept of natural selection.

Back

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

Front

What is genetic diversity?

Back

The total number of genetic characteristics in the genetic makeup of a species.

Front

Define directional selection.

Back

A type of natural selection that favors one extreme phenotype over the mean or other extreme phenotypes.
