i was just wondering...

 I am a carrier of cystic fibrosis and DH is not does that mean DS is a carrier or does he have a chance of not being a carrier. and is that all my children will be is carriers?

*blondie*

Uhh, ??? Google? Sorry, I have no idea.

Yes. You need both to have CF, but only one copy (from you) to be a carrier.

 

ETA: That is wrong. It would depend of if LO inherts the mutated gene or the non-mutated one from you.

Do you know if it's a sex-linked trait? As in, do you know if it's carried on the X-chromosome?

im not sure. i know that because DH is not a carrier then my children do not have a chance of having it but they may be a carrier. but my question is it like a 50/50 chance?

 yes. 50/50 that they will be a carrier

Since you are a carrier and your DH does not have it at all, there is a 50% chance that your LO is a carrier.  This chance is the same for each of your children, independent of each other.

Your DH does not have the mutation at all so any genes he passes on will not have the mutation.  You have the mutation to one, but not both of your genes (everyone has 2 sets of genes) so you have a 50/50 chance of passing it on to your children.  Since each child is an independent creation, the risk does not change as you have more (or less) children.
