Question

Above pedigree chart show

• A. Autosomal dominant trait
• B. Sex-linked recessive trait
• C. Autosomal recessive trait
• D. Sex-linked dominant trait

Answer 1

The correct option is A Autosomal dominant trait

The pedigree chart is a diagrammatic representation of the appearance of a particular trait in a family over generations. It is used to determine the inheritance of traits. The given pedigree chart shows dominant trait as it is present in all the generation. A recessive trait is seen in alternate generations. It is an autosomal trait as it is affecting male and female equally. Sex-linked traits affect a particular sex more.

Thus, the correct answer is 'Autosomal dominant trait.'
