Mendelian Genetics
Mendelian genetics, pioneered by Gregor Mendel in the 19th century, revolutionized our understanding of heredity. This fundamental branch of genetics elucidates the principles governing the transmission of traits from one generation to the next. Mendelian genetics explores the inheritance patterns of traits controlled by single genes, providing a cornerstone for modern genetic research. Through controlled breeding experiments with pea plants, Mendel uncovered the principles of dominance, segregation, and independent assortment, laying the groundwork for the field of genetics as we know it today. Understanding Mendelian genetics is essential for unraveling the complexities of inheritance and genetic variability in organisms.
Questions
