According to genetics the probability is very high and in case your kids will not have this gene then your grand children must have the gene. Genes like shortness or tallness are always transfered to the offsprings. On the other hand, there are certain genes that we cannot see, for instance, asthma, colour blindness, albinism among others. From the look of someone, you will not know if they're carrying these genes.Something with these genes is that they're mostly carried with the females and that's why its said that women are carriers. As a matter of fact, before marriage its highly recommended that you do a back ground check up on the family first so that you don't end being surprised one day giving kids with those genes.Also, there are certain genes which are mostly carried with the men like tuft(hairs in the nose and ears) and baldness. These two will forever remain in your lineage no matter what.
