Worked Solution & Example Answer:Sutton, Boveri and Morgan worked in the field of genetics - HSC - SSCE Biology - Question 21 - 2001 - Paper 1
Step 1
Contribution of Sutton
Answer
Sutton proposed the chromosome theory of inheritance, which states that genes are located on chromosomes. This theory was fundamental in understanding how traits are inherited from one generation to the next. He argued that during gamete formation, chromosomes segregate independently, leading to genetic variation.
Step 2
Contribution of Morgan
Answer
Morgan conducted experiments with Drosophila (fruit flies) and demonstrated that specific traits are associated with specific chromosomes. His work established the principles of sex-linked inheritance, showing how certain traits can be carried on sex chromosomes, thereby influencing inheritance patterns in offspring.
