Front

What is a random change in an allele called?

Back

Mutation

Front

What is the term for selective breeding of domesticated plants and animals to produce offspring with desired genetic traits?

Back

Artificial selection

Front

What is the definition of mutation?

Back

A random change in the DNA sequence of an organism.

Front

What does the term 'artificial selection' refer to?

Back

The process by which humans breed plants and animals for particular genetic traits.

Front

What is the significance of the Hardy-Weinberg principle in population genetics?

Back

It provides a mathematical model to study genetic variation in a population.

Front

What are the conditions required for a population to be in Hardy-Weinberg equilibrium?

Back

No mutations, random mating, no natural selection, large population size, and no gene flow.

Front

What is stabilizing selection?

Back

A type of natural selection that favors average phenotypes and selects against extreme variations.
