Question

Although Haemophilia and sickle cell anemia are two blood-related Mendelian disorders, yet, they differ in their pattern of inheritance. State any two differences.

Answer 1

Analyze the inheritance of Haemophilia.
- Haemophilia is a sex-linked recessive disorder, predominantly affecting males who have only one X chromosome.
Analyze the inheritance of sickle cell anemia.
- Sickle cell anemia is an autosomal recessive disorder, meaning both males and females are equally affected because it is inherited through autosomes, not sex chromosomes.
1. Haemophilia is a sex-linked recessive disorder, while sickle cell anemia is an autosomal recessive disorder.
2. Haemophilia predominantly affects males, whereas sickle cell anemia affects both sexes equally.
