The significance of T.H. Morgan's discovery of sex-linked traits is that it provided strong evidence for the Chromosomal Theory of Inheritance. Morgan's discovery that the gene for eye color in fruit flies was located on the X chromosome and showed sex-linked inheritance was a significant breakthrough in the field of genetics. This discovery supported the idea that genes are located on chromosomes and are transmitted through the process of meiosis. Morgan's work laid the foundation for the field of genetics and has contributed significantly to our understanding of how genetic traits are passed down from parents to offspring.

Option 3 is the correct answer.
