Is dwarfism dominant or recessive?
Understand the Problem
The question is asking whether dwarfism is inherited in a dominant or recessive manner, which refers to the genetic patterns of inheritance for dwarfism.
Answer
Dwarfism can be dominant or recessive.
Dwarfism can be inherited in both dominant and recessive manners. The most common form, achondroplasia, is inherited in a dominant manner, while other forms like diastrophic dysplasia are recessive.
Answer for screen readers
Dwarfism can be inherited in both dominant and recessive manners. The most common form, achondroplasia, is inherited in a dominant manner, while other forms like diastrophic dysplasia are recessive.
More Information
Achondroplasia, the most common form of dwarfism, is usually inherited in a dominant manner, meaning only one copy of the altered gene is needed. Other types, like diastrophic dysplasia, require two copies of the mutated gene, one from each parent, to be inherited.
Tips
A common mistake is to assume all forms of dwarfism are inherited in the same manner. Not all are; some forms are recessive while others are dominant.
