What led scientists accepting Mendelssohn ideas?

Scientists began accepting Mendel's ideas due to the resurgence of interest in his work during the early 20th century, particularly when researchers like Hugo de Vries, Carl Correns, and Erich von Tschermak independently confirmed his findings on inheritance patterns. The establishment of the field of genetics and the discovery of chromosomes provided a biological basis for Mendel's principles, aligning his theories with observable phenomena in cell division and heredity. Additionally, the application of Mendelian principles to breeding experiments in agriculture further validated his concepts, leading to widespread acceptance among the scientific community.
