All of the following are non-allelic X-linked traits except:
Correct answer: B. Hemophilia C
- A. Hemophilia A
- B. Hemophilia C
- C. Hemophilia B
- D. TFM syndrome
Explanation
Haemophilia A and B are non-allelic recessive sex-linked but hemophilia C is an autosomal recessive trait (Autosome 4). Testicular feminization is the syndrome when a male, genetically XY, because of various abnormalities of the X chromosome, is resistant to the actions of the androgen hormones

About Inheritance
Mendel's laws explain segregation, independent assortment and the prediction of genetic ratios using alleles, genotypes and phenotypes. The chapter also covers linked genes, recombination and crossing over during meiosis, then applies pedigree reasoning to X-linked recessive traits, which show different inheritance patterns in males and females.
