Genetics are complicated!. But if two parents both carry a recessive gene!. You would get :
1/4 chance the child is normal
2/4 chance the child is a carrier-has the recessive gene
1/4 chance the child has the trait or the disease
There are many recessive traits and diseases-blue eyes, muscular dystrophy's and many more!.
There is genetic counseling if you are concerned about having a child with SMA!.
