Linked Genes

Key Questions

  • Linked genes are genes that are located on the same chromosome.

    Hence they are passed down together, and their phenotypes are often found together. An example of this would be the genes for red hair and freckles, which you usually see together in people.

    That is a basic overview of what they are. If you'd like to learn more, I encourage you to watch this video by Bozeman Biology:

    X-linked traits are sex-linked traits determined by genes on the X-chromosome. Some X-linked traits in humans are; red-green colorblindness, Duchenne muscular dystrophy, hemophilia A, and hemophilia B. These are all recessive traits, and affect males with a much greater frequency than females.

    There are also Y-linked traits on the Y-chromosome that are passed exclusively from father to son. One of these genes is the #"SRY"# gene called the "sex determination region Y gene." It controls the development of the male sex characteristics in a developing male fetus.
