Education
Theodor Boveri's & Walter Sutton's Education
Theodor Boveri
- graduated from Realgymnasium in 1881
- entered University of Munich in 1881
- 1885 He began a series of studies on chromosomes
- Theodor Boveri became an apprentance to Carl von Kupffer
- His exploration for evidence-sea urchin double fertilization observation
- Observed how abnormal chromosomes numbers affects development
- interested in offspring attributes in relation to parents
- research on sea urchn served to provide importance of Maternal and Paternal material
- Sea Urchin Embryo are transparent-easier analyzation and tracing of development
Walter Sutton
- studied grasshoppers
- connected the phenomena of meiosis, segregation, and independent assortment with the chromosomal theory.
- Walter Sutton graduated from Kansas University in 1896
- received a master's degree
- changed education from engineering to the medical field
- published "The Spermatogonial Division of Brachystola magna" in 1906

Life After College
- During college, Boveri wrote his disteration: Beiträge zur Kenntnis der Nervenfasern
- he was awarded a doctorate, a Lamont-Stipendium Fellowship
- shortly after his 30th birthday, was offered the opputurnity as a Professor at Wurzberg, Germany, in Zoology and Comparitive Anatomy
- beginning in 1890, Boveri had severe health issues
- Boveri was able to reach two additional, important conclusions about the nature of hereditary processes
- In the summer of 1903, Sutton stopped studying developmental biology to work in the Kansas oil fields to earn money for medical school
- Sutton received his MD degree in 1907 & began an internship at Roosevelt Hospital in New York
- Sutton became associate professor of Surgery at University of Kansas
- awarded an affiliation at Bell Memorial Hospital
- In 1915, the military hired Sutton as part of the surgical staff during WWI
- he became chief of the surgical staff and soon died after his tour
Research
- Both Boveri and Sutton researched chromosomes and their heredity
- Sutton followed and continued Boveri's studies
- Boveri began to understand the events that take place in the nucleus of the cell
- The significance of Mendel and Boveri's work emphasized by Sutton
- Boveri linked chromosomes and heredity together
- Boveri took Flemming's findings to provide evidence of germ cell linage
- Boveri observed Ascaris/simple chromosome display
- demonstatred each chromosome carried heriditary information
Conclusions
Conclusions
- Sutton described the configurations of individual chromosomes in cells at various stages of meiosis
- Sutton was able to identify 11 pairs of chromosomes - also discovered a single chromosome that is presumed to be a sex chromosome
- Boveri brought the intial connection between chromomes and the path to our knowedge of Meiosis and fertilization (Haploid to Diploid)
