An American couple both work in an atomic energy plant, and both are exposed daily to low-level background radiation. After several years, the couple got it on, made a baby, and this baby got this disease thang called Duchenne muscular dystrophy, a sex-linked recessive genetic defect in which the mutant locus is on the X chromosome. Both parents are normal, as are the grandparents. The couple sue the plant claiming that the abnormality in their child was the direct result of radiation-induced mutation of their gametes, radiation against which the company should have protected them. Before reaching a decision, the judge insists on knowing the sex of the child. Which sex would be more likely to result in an 'award' of damages, and why?

Thank you.please.really.help.me.now.thanks.yeah.help.yeah.bye.
 
If the disease is sex-linked recessive on the x chromosome, the baby would need to have two x chromosomes to have it, and would be a girl, if the disease were genetically inherited. So if the baby is a girl, there's no way to tell whether it has been radiation-induced. If it's a boy, the disease must be radiation-induced; since it could not be inherited.
