Use the diagram below to answer the question.
The genetic event shown in the diagram can occur during meiosis. Which statement best describes this type of event?

Gene sequences that are identical are replicated and added to the homologous chromosome.

Sections of DNA between nonhomologous chromosomes are exchanged, decreasing genetic diversity.

Segments of homologous chromosomes are exchanged, resulting in cells that will be genetically different.

The traits from two sections of the same DNA strand are altered, resulting in the production of a new species.

Females produce far more gametes than males do

Sperm and ova (egg) are not identical to the parent cells that produced them

The process begins in males and females at the same time

Meiosis in males creates genetic diversity, but not in females

What is a likely evolutionary advantage of sexual reproduction over asexual reproduction?

Sexual reproduction is more metabolically efficient.

Sexual reproduction results in variation in the offspring.

Sexual reproduction uses up fewer resources in a given environment.

Sexual reproduction involves fewer steps.

Match the following with the correct type of cell division

More complex and contains two divisions
Results in the production of gametes
Final cell has only half of the parent's DNA

The main difference between meiosis and mitosis is that ...

During mitosis, sister chromatids separate; they do not during meiosis.

Mitosis increases chromosome number in each cell, while meiosis decreases it.

Mitosis makes genetically identical copies; meiosis does not.

DNA replicates during mitosis, but does not during meiosis.
