Hemophiliac's blood fails to clot properly after an injury, because of the following reasons, EXCEPT:
Correct answer: D. A reduction in hemopoitic stem cells
- A. A reduction of blood clotting factors
- B. A malfunction of blood clotting factors
- C. A complete absence of blood clotting factors
- D. A reduction in hemopoitic stem cells
Explanation
Hemopoietic stem cells are responsible for producing blood cells, including platelets, which play a crucial role in the blood clotting process. If there is a reduction in hemopoietic stem cells, it can lead to various blood disorders, but it is not directly related to hemophilia.

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.
