Mr. Anderson introduces AP Biology Lab 3, focusing on mitosis and meiosis. The lab involves observing cell division in onion roots to understand mitosis phases and using sordaria fungus to study genetic crossover in meiosis. Mitosis is explained as the equal division of the nucleus, resulting in identical diploid cells. Meiosis involves two divisions and genetic crossover, producing haploid cells with unique genetic combinations. The lab procedures include counting cell phases in mitosis and analyzing spore patterns in meiosis to determine crossover frequency.
