Back

To produce gametes (sperm and egg cells) with half the number of chromosomes.

Front

What are homologous chromosomes?

Back

Chromosome pairs, one from each parent, that are similar in shape, size, and genetic content.

Front

What is crossing over in Meiosis?

Back

The exchange of genetic material between homologous chromosomes during Prophase I.
