If someone who is homozygous for an autosomal recessive disorder mates with a person who does
not carry the mutated gene their child will
have a 100 percent chance of developing the disease
have a 25 percent chance of developing the disease
have a zero percent chance of developing the disease
have a 50 percent chance of developing the disease

have a zero percent chance of developing the disease
