Correct answer: C. Morgan
- A. Sutton
- B. Fleming
- C. Morgan
- D. Landsteiner
Explanation
Before Morgan there was speculation about role of chromosomes in inheritance but no one had proved it experimentally. Morgan performed experiments on fruit fly and he concluded that eye color in Drosophila resides on X chromosome. This shows that genes for all traits are present on different chromosomes.

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
