Question

which statement best defines genetic variation?
the diversity of inherited traits within a population.
the traits an organism acquires during its lifetime.
the process of a population moving to a new area.
the way all members of a population look identical.

Explanation:

To determine the correct statement for genetic variation, we analyze each option:

• The first option: "The diversity of inherited traits within a population" matches the definition of genetic variation, as genetic variation refers to the differences in inherited (genetic) traits among individuals in a population.
• The second option describes acquired traits (not genetic, as genetic traits are inherited, not acquired during a lifetime).
• The third option refers to migration (a different evolutionary mechanism, not genetic variation).
• The fourth option describes phenotypic uniformity, not variation.

Answer:

The first option (top - "The diversity of inherited traits within a population")
