Question

Two parents of normal phenotype have a son with an autosomal recessive linked genetic disorder. What is the most likely cause of this?

Answer 1

Answer:

Who is “affected” When both parents are carriers for a recessive disorder, each child has a 1 in 4 (25 percent) chance of inheriting the two changed gene copies. A child who inherits two changed gene copies will be “affected,” meaning the child has the disorder.
