Which statement correctly distinguishes between linked genes and sex-linked genes?

  • A: Linked genes are on the same chromosome, while sex-linked genes are on sex chromosomes.
  • B: Linked genes are always inherited together, while sex-linked genes are not.
  • C: Sex-linked genes are on the same chromosome, while linked genes are on different chromosomes.
  • D: Both terms describe the same phenomenon.

Explanation

Linked genes are any genes located near each other on the same chromosome autosome or sex chromosome . Sex-linked genes are specifically those genes located on a sex chromosome X or Y . Therefore, two genes can be both sex-linked and linked to each other e.g., two genes close together on the X chromosome .
