Understanding Genetics: Meiosis, Mendel’s Laws, and Blood Typing Explained

Explore the fascinating world of genetics through key concepts such as meiosis, Mendel's laws, and blood typing. Learn about the steps of meiosis and how it differs from mitosis, the significance of the law of segregation and independent assortment, and exceptions to these laws. Delve into Mendel's experiments and solve genetics problems, including monohybrid and dihybrid crosses. Understand blood typing, including antigens, antibodies, and donor-recipient compatibility. Analyze karyotypes and discover chromosomal syndromes and their characteristics.
