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

Explain the causes, inheritance pattern and symptoms of any two Mendelian genetic disorders .

Explain the causes, inheritance pattern and symptoms of any two Mendelian genetic disorders.

A cross between a normal couple resulted in a son who was haemophilic and a normal daughter. In course of time, when the daughter was married to a normal man, to their surprise, the grandson was also haemophilic. a) Represent this cross in the form of pedigree chart. Give the genotypes of the daughter and her husband. b) Write the conclusion you draw of the inheritance pattern of this disease.

Haemophilia is a sex linked recessive disorder of humans. The pedigree chart given below 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 gaemophilia. The member numbered 15 has recently married the member numbered 14. What is the probability that their first child will be a haemophilic male ? Show with the help of Punnett square.
