The genes located on homologous regions of X and Y chromosomes do not inherit together because crossing over occurs in this region. Thus, they exhibit incomplete sex linkage. They are called the X-Y linked traits. Which of the following is NOT an example of X-Y linked traits?
Options
- ATotal colour blindess.
- BNephritis.
- CMyopia.
- DRetinitis pigmentosa.
Correct answer
C. Myopia.
Step-by-step solution
Genes located on the homologous regions of X and Y chromosomes are known as incompletely sex-linked genes or X-Y linked genes. Because crossing over can occur in these homologous regions, these traits do not always inherit together.
Common examples of X-Y linked traits in humans include total colour blindness, nephritis, retinitis pigmentosa, xeroderma pigmentosum, and epidermolysis bullosa.
Myopia is not an X-Y linked trait. It is generally inherited as an autosomal or X-linked trait.
