Translate between words, diagrams, symbols, tables and graphs without changing the underlying meaning.

This extension applies that lens specifically to Meiosis and Variation.

Meiosis and Variation

Meiosis produces haploid gametes through two divisions. Crossing over and independent assortment generate variation, while nondisjunction can alter chromosome number.

Core checkpoint: Separate the reduction in chromosome number from the sources of genetic variation.
