A diseased man marries a normal woman. They get three daughter and five sons. All the daughter were diseased and sons were normal.The gene of this disease is
- Sex linked dominant
- Sex linked recessive
- Sex limited character
- Autosomal dominant
The Correct Option is A
Solution and Explanation
The correct option is (A) : Sex-linked dominant
The daughter inherits the "X-chromosome" from the father, while the "Y-chromosome" is passed down to the boys. The characteristic is X-linked since only the daughter and none of the boys are impacted. Daughters get the second X chromosome from their normal mother, who does not possess the trait's problematic allele. The characteristic is an X-linked dominant trait since it is manifested in daughters under heterozygous conditions.

- Consider the diameter of a spherical object being measured with the help of a Vernier Callipers. Suppose its 10 Vernier Scale Divisions (V.S.D.) are equal to its 9 Main Scale Divisions (M.S.D.). The least count in the M.S. is 0.1 cm and the zero of V.S. is at -0.1 cm when the jaws of Vernier callipers are closed. If the main scale reading for the diameter is \(M = 5\) cm and the number of coinciding vernier division is 8, the measured diameter after zero error correction, is:

Mendelian Disorders
Mendelian Disorder is a type of genetic disorder that is caused due to alterations in one gene or abnormalities in the genome. These disorders can be seen since birth and can be deduced using the Pedigree Analysis.
