Sutton, Boveri, and Morgan
To determine the basis for genetic inheritance
1902 - Boveri studied reproduction in sea
urchins, while Sutton was studying meiosis
in sea creatures, specifically the fact that
during meiosis, the number of chromosomes
in sex cells is halved
1915 - Morgan studied heredity in fruit flies
Chromosomes carry genes from one
generation to the other, and a specific set of
chromosomes is necessary for normal growth (jan 1, 1902 – jan 1, 1915)
