उत्तर
Sex linkage refers to the phenomenon where genes are located on the sex chromosomes, usually the X chromosome, and their inheritance is linked to the sex of the individual. Sex-linked traits are passed from parents to offspring through these chromosomes, leading to different patterns of inheritance in males and females. For example, in humans, disorders like hemophilia and color blindness are sex-linked, predominantly affecting males because they have only one X chromosome. Thomas Hunt Morgan's work on fruit flies established the concept of sex linkage by studying eye color traits inherited differently in males and females due to genes on the X chromosome.
