Meiosis

Explore the intricacies of meiosis in this comprehensive 52-minute lecture by Dr. Najeeb. Delve into the process of gametogenesis, including oogenesis and spermatogenesis, and understand the crucial role of meiosis in creating genetic diversity. Learn about diploid early germ cells, homologous chromosomes, and the significance of genes and alleles. Discover the details of DNA replication, chromosome duplication, and the formation of chromatids. Examine the meiotic division process, including the creation of primary gametes and the key differences between meiosis I and mitosis. Understand the importance of synapsis, crossover, and chiasma in generating unique genetic material. Follow the alignment and disjunction of chromosomes, leading to the creation of secondary gametes. Analyze the final stages of meiosis II, resulting in haploid single-structured chromosomes. Gain insights into the differences in meiosis between males and females, and grasp the ultimate purpose of meiosis in promoting genetic diversity.
