Final answer:
An autosomal recessive disorder is caused by inheriting two copies of a recessive gene from both parents. Both parents must be carriers of the gene but do not have the disorder themselves.
Step-by-step explanation:
An autosomal recessive disorder is a genetic condition that is caused by inheriting two copies of a recessive gene, one from each parent. To inherit the disorder, both parents must be carriers of the recessive gene, meaning they have one copy of the gene but do not have the disorder themselves. When both parents are carriers, there is a 25% chance for each child to inherit the disorder.
