a) The High incidence of still birth could be due to both parents carrying a defective copy of Chromosome one. There is a 25% chance of inheriting both copies from parents. The parents are unaffected because they have a normal copy but are carriers of the abnormal copy.

b)There is a possibility that the children are all normal and 50% of them will be carriers or the abnormal chromosome. This is only likely if the woman has two normal copies and no other underlying mutations.

c)There are now advancements in fertility and her options are many. She can opt for <em>in vitro</em> assistance where the affected male gametes are filtered out. Also she can do various tests while the child is still in the womb to determine the genetic predisposition. Decisions can be made after the results are given.

It is highly suggested that this woman and her husband undergo genetic counselling if they are to fully understand their condition and produce healthy children.
