Question

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 

• A. Sex linked dominant
• B. Sex linked recessive
• C. Sex limited character
• D. Autosomal dominant

Answer 1

The Correct Option is A

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.
