The most common type of haemophilia results from the congenital absence of
1 factor-II
2 factor-V
3 factor-VIII
4 factor-XI
Explanation:
: The most common type of haemophilia results from the congerital absence of factor VIII. Haemophila is a sex-linked recessive disease which shows its transmission from unaffected carrier female to some of the male progeny. In this disease, a protein involved in the clotting of blood is affected.

Down's syndrome is due to
1 Trisomy of \(21^2\) chromosome
2 Tetrasomy of \(22^{\text {th }}\) chromosome
3 Polysony of \(9^{\text {th }}\) chromosome
4 Monosomy of \(21^{\text {a }}\) chromosome
Explanation:
: Down syndrome, also known as trisomy 21. it is a genetic condition that is primarily due to an extra copy of chromosome 21. It can occur due to errors during the formation of teproductive cells (egg or sperm) or during early fetal development.

Sickle cell anemia is an example of
1 Chromosome mutation
2 Point mutation
3 Genetic recombinations
4 Enviromental effect
Explanation:
: Sickle cell anemia is an example of a point mutation. It is caused by a specific mutation in the betaglobin gene, which encodes a part of hemoglobin, the protein responsible for carrying oxygen in Red blood cells. This mutation results, in the substitution of one mucleotide (adenine, A) for another (thymine, \(\mathbf{T}\) ).
