Population Genetics: When Darwin Met Mendel - Crash Course Biology

The video explores the foundational concepts of genetics and evolution, focusing on the contributions of Gregor Mendel and Charles Darwin. It introduces population genetics, explaining how allele frequencies change due to factors like natural selection, sexual selection, mutation, genetic drift, and gene flow. The Hardy-Weinberg principle is discussed, providing a framework for understanding genetic stability in populations. The video concludes with a practical application of the Hardy-Weinberg equation to calculate allele and genotype frequencies, illustrating the interplay between Mendelian genetics and population dynamics.
