This is the pedigree of a family tracing the movements of the gene for haemophilia. Explain the pattern of inheritance of the disease in the family.

Haemophilia is a sex-linked recessive disorder of humans. The given pedigree chart shows the inheritance of haemophilia in one family. Study the pattern of inheritance and answer the questions given. (a) Give all the possible genotypes of the members 4, 5 and 6 in the pedigree chart. (b) A blood test shows that the individual 14 is a carrier of haemophilia. The member number 15 has recently married the member numbered 14. What is the probability that their first child will be a haemophilic male?

give an example of an ausomal reessive trait in humans Explain its pattern of inheritance with the help of a cross .

Why are thalassemia and hemophilia categorized as Mendelian disorders ? (a) Write the symptoms of these diseases. Explain their pattern of inheritance in humans. ( b) Write the genotypes of the normal parents producing a hemophilic son.

Assertion: Mendelian disorders are transmitted to offspring on the same lines as in the principles of inheritance. Reason: The pattern of inheritance of Mendelian disorders cannot be traced in a family by the pedigree analysis.

(a) Why is it that the father never passes on the gene for haemophilia to his sons? Explain. (b) State the functions of the following in a prokaryote : (i) tRNA, (ii) rRNA

Write the symptoms of haemophilia and sickle-cell anaemia in humans. Explain how the Inheritance pattern of the two diseases differs from each other.

Sickle cell anaemia follows the same inheritance pattern as that haemophilia.
