When was Mendel proven right?

Gregor Mendel's principles of inheritance were largely ignored during his lifetime, but his work was rediscovered in the early 20th century, particularly around 1900. Scientists such as Hugo de Vries, Carl Correns, and Erich von Tschermak independently confirmed Mendel's findings on heredity, leading to the establishment of modern genetics. This validation cemented Mendel's status as the father of genetics, confirming his theories about dominant and recessive traits.
