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.
