Genetics and Reproduction

Which statement best explains how organisms accomplish passing on traits to their offspring?

• Traits are acquired when parents care for their offspring.

• Offspring inherit traits when DNA is replicated during mitosis.

• Traits are inherited by the transfer of genetic material from parent to offspring.

• Offspring acquire traits when cells become specialized for certain functions.

In humans, which pair of chromosomes determines the sex of an individual?

• XY chromosomes

• XX chromosomes

• YY chromosomes

• ZZ chromosomes

How does genetic variation contribute to the survival of a species?

• It ensures that all offspring will have the same traits as their parents.

• It increases the risk of genetic disorders within a population.

• It allows for adaptation to changing environments.

• It reduces the need for sexual reproduction.
