Beyond the Punnett Square: How Chromosomes Actually Move
In short: Most people learn genetics through simple squares, but the real action happens at the chromosomal level. This video breaks down how genes are physically distributed during meiosis to create genetic diversity.
Paul Andersen explores the mechanics of inheritance by moving from basic Mendelian monohybrid crosses to the complex distribution of genes during meiosis. The video illustrates how specific genes are passed to gametes, providing a visual map of genetic inheritance.
The exploration deepens into dihybrid crosses and the phenomenon of gene linkage. By understanding these processes, viewers can see how physical proximity on a chromosome influences how traits are inherited, moving beyond simplified models into the actual biological machinery of heredity.
