Meiosis and Variation: Mechanism
≈ 32 minMechanism
Follow the mechanism step by step and distinguish what causes the change from what is merely observed.
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.
