As a genetic counselor, you are visited by two families, each of which has a child with Down syndrome (Trisomy 21).  In Family A, the trisomy 21 child has inherited a 21q21q isochromosome from the mother, who does not have Down syndrome.  The father in this family has a normal karyotype.  In Family B, both parents have a normal karyotype.  What would you tell each family about their risk for bearing another child with Down syndrome?  Explain you reasoning.
