Question

Which is a dominant genetic disorder?

Answer 1

Answer:

The correct option is A) achondroplasia

Explanation:

Achondroplasia is a genetic disorder which is caused in an autosomal dominant pattern. This means that an individual who even has a single allele for the gene will have the disorder. This is because a dominant allele masks the effect of the recessive allele.

Achondroplasia is a disorder in which the cartilage of the long bones of the arms and legs does not get converted into bones. It is a type of dwarfism.
