Meiosis, Sexual Reproduction, & Genetic Variability science DVD

Begins by comparing asexual and sexual reproduction and describing chromsomes and homologous pairs. The difference between haploid and diploid cells and the three major eukaryotic life cycles are then described. The program goes on to a detailed description of all the stages of Meiosis I and II including prophase I and II, metaphase I and II, anaphase I and II, and telophase I and II. In the process students are introduced to phenomena such as crossing over and provided an explanation of how meiosis creates genetic variability in a species.
