Dear student
 
Please ask only one question in one thread.
 
1.)
 
  • Boveri and Sutton's chromosome theory of inheritance states that genes are found at specific locations on chromosomes, and that the behavior of chromosomes during meiosis can explain Mendel’s laws of inheritance.
  • Thomas Hunt Morgan, who studied fruit flies, provided the first strong confirmation of the chromosome theory.
  • Morgan discovered a mutation that affected fly eye color. He observed that the mutation was inherited differently by male and female flies.
  • Based on the inheritance pattern, Morgan concluded that the eye color gene must be located on the X chromosome.
