About $7,000. there are more wholesale or retail firms which for 99 bucks you can get your 200 chromosomes. so we've always thought forewarned is forearmed. and the problem is that there's lots of things we can find out and know about that we can't do anything about. so do you really want to know that that little baby girl has genes that are likely to -- that she'll get dementia or parkinson's disease or things that we can't really do too much about? it's great to know that if you're liable to be diabetic, for example, then you could do something about your child's diet. but i do think, you kn...
