This document discusses the process of meiosis. Meiosis involves two rounds of cell division that result in four daughter cells with half the number of chromosomes as the original parent cell. The key steps mentioned are crossing over, which leads to genetic recombination, and the two divisions - reductional division which separates homologous chromosomes and equational division which separates sister chromatids. Links are provided to interactive exercises and animations explaining these stages of meiosis.
