Pick up the choice not true with respect to both hemophilia A and hemophilia-B:
Correct answer: C. Allelic
- A. Non-allelic
- B. Recessive
- C. Allelic
- D. Sex linked
Explanation
"Allelic" means that two different traits or disorders are caused by mutations in the same gene. However, as mentioned earlier, hemophilia A and hemophilia B are caused by mutations in different genes (F8 and F9, respectively), making them non-allelic disorders.

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.
