Which one of the following is NOT an example of complete sex...
Which one of the following is NOT an example of complete sex linkage ?
Options
- ARed-green color blindness
- BMyopia
- CNephritis
- DHaemophilia
Correct answer
C. Nephritis
Step-by-step solution
Complete sex linkage refers to the inheritance of genes located on the non-homologous regions of the X and Y chromosomes, which do not undergo crossing over. Examples of completely sex-linked traits in humans include red-green colour blindness, haemophilia, and myopia.
Incomplete sex linkage involves genes located on the homologous regions of the X and Y chromosomes, which can undergo crossing over. Examples of incompletely sex-linked traits include total colour blindness, retinitis pigmentosa, and nephritis.
Therefore, nephritis is an example of incomplete sex linkage, not complete sex linkage.
Answer: Nephritis
Incomplete sex linkage involves genes located on the homologous regions of the X and Y chromosomes, which can undergo crossing over. Examples of incompletely sex-linked traits include total colour blindness, retinitis pigmentosa, and nephritis.
Therefore, nephritis is an example of incomplete sex linkage, not complete sex linkage.
