Question

Queen Victoria was carrier of this disease. above facts which disease is discussed ? how it is communicated ? why there is rare probability in woman suffering from this disease?​

Answer 1

Explanation:

The family pedigree of Queen Victoria shows a number of hemophilic descendants because hemophilia is sex-linked recessive disorder and Queen Victoria was a carrier. X-linked recessive or sex-linked recessive disease most often occurs in males because Males have only one X chromosome. A single recessive gene on that X chromosome will cause the disease. Females have two X chromosomes so they can act as carriers for the disease. Hemophilia is a bleeding disorder that slows the blood clotting process.

So, the correct answer is 'Haemophilia is sex-linked recessive disorder and Queen Victoria was a carrier'.
