"Human Genetics is the study of heredity and variation in humans. It explains how genes and environment together shape traits like height, eye colour, and behaviour. The science began with Gregor Mendel’s pea plant experiments in 1866. His Law of Segregation showed that parents pass only one allele to offspring by chance, while his Law of Independent Assortment explained how different traits are inherited independently, creating variation. In the early 1900s, scientists rediscovered Mendel’s work, linked it with chromosomes, and coined the terms gene and genetics. A major breakthrough came in 1953, when Watson and Crick discovered the DNA double helix, launching the molecular era. Today, Human Genetics helps us understand human nature, diagnose genetic diseases, develop treatments like gene therapy, provide genetic counseling, and even solve crimes using DNA fingerprinting. In short: Human genetics explains heredity, supports medicine, and answers the classic nature versus nurture debate."
