  1. The chromosome theory of inheritance is credited to papers by Walter Sutton in 1902 and 1903, as well as to independent work by Theodor Boveri during roughly the same period. Boveri was studying sea urchins , in which he found that all the chromosomes had to be present for proper embryonic development to take place. [8]

He developed the chromosomal theory of inheritance and the idea of chromosomal individuality. Boveri sought to provide a comprehensive explanation for the hereditary role and behavior of chromosomes.

  8. Walter Sutton, he studied grasshoppers. Theodor Boveri, he studied sea urchins, but they looked at meiosis, and they looked at the reproduction and the fertilization during these processes. And they saw that the chromosomes seemed to do things that were very similar to these laws of segregation, laws of independent assortment, laws of dominance.
