Gregor Mendel conducted experiments with pea plants in the 1860s to study inheritance patterns. He discovered that traits are passed from parents to offspring according to specific laws. Mendel's two major laws were the Law of Segregation, which states that organisms have two versions of each gene that separate during reproduction, and the Law of Independent Assortment, which explains that different genes are passed down independently of one another. Though his work was initially dismissed, it formed the basis for modern genetics when it was rediscovered in 1900.
