Suppose you are genetic counselor, named Jean (Gene) O’ Type and
two couples seek your advice and counseling. Peter and Paula have
been trying to conceive a child for the past 15 months without
success. Sam and Susan are already pregnant, but they are concerned
about having a child with sickle cell anemia and want to be
prepared both emotionally and medically for the child’s special
needs as soon as it is born. Both couples are worried and
concerned.

Explain two different biological facts you would tell Peter and
Paula to help them better understand their fertility problem.
