A member asked:

If my twin brother has hemophilia but i don't, what are the chances that my kids will develop it?

Depends on sex: If the unaffected twin is male he would not carry the gene and could not pass it on to his children. If the unaffected twin was female she could be a carrier and could pass the gene on to her children. If she did her male children would be affected and her female children would be carriers.

High for your sons: It seems like you are a carrier, since your brother twin have disease. The hemophilia is linked to x-chromosome, so 1/2 of your sons will develop it, if you husband is healthy.
