Question

Identify the category of genetic disorder depicted in the pedigree chart given below:

विकल्प

• X-Linked recessive

• X-Linked dominant

• Autosomal recessive

• Autosomal dominant

Answer 1

Autosomal recessive

Explanation:

• Gene mutations on non-sex chromosomes are the primary cause of disorders in autosomal recessive inheritance. In this pattern, both parents of an affected person who are unaffected carriers typically carry the gene.
• Therefore, the presence of multiple siblings in a family affected and their parents who are unaffected carriers indicates autosomal recessive inheritance.
