If you or your family has a history of a detrimental genetic condition, do you risk passing it on by having children? I went to high school with a couple of girls who had a brother with cerebral palsy. There was a history of the disorder in males on their mother's side of the family. One of the girls decided that she didn't want to take the chance of passing on the condition by having biological children. This was back in the early 1960s. Thalidomide also caused many birth defects and it appears that some can be passed on to offspring. Dwarfism seems to cause a lot of problems for those who have it and it may or may not be passed on genetically. On a Shriner's hospital ad I see a woman with no arms using her feet to comb the hair of a boy with no arms. I assumed it was her child but there was no mention of it. I think it would weight quite heavily on my mind and would certainly be considered.
