Mendel discovered that when crossing purebred plants, the traits of the offspring exhibited a predictable pattern of inheritance. He found that certain traits were dominant, meaning they would appear in the offspring even if only one parent contributed the dominant allele. This led to the realization that traits are passed down in discrete units (now known as genes), and that variation in these traits can be observed in subsequent generations. His experiments laid the groundwork for the principles of heredity, including the concepts of dominant and recessive traits.
