Which trait is not sex-linked recessive:
Correct answer: C. Hypophosphatemic ricket
- A. Haemophilia
- B. Colour blidness
- C. Hypophosphatemic ricket
- D. TFM syndrome
Explanation
Hypophosphatemic rickets is an X-linked dominant trait in which excessive loss of phosphate in the urine leads to poorly formed bones (rickets), bone pain, and tooth abscesses. ADHR is caused by a mutation in the fibroblast growth factor 23 (FGF23). This way although phosphates are produced in the body but not recognized by the receptors on bone cells.

About X-linked Recessive Inheritance
X-linked recessive inheritance involves genes on the X chromosome, so males express a recessive allele with no corresponding allele on their single X chromosome, while females may be carriers. Pedigrees cover haemophilia and red-green colour blindness, including carrier mothers, affected sons and the absence of father-to-son transmission.
