The Short Answer

Members of the same family can have the same recessive genes that can cause defects – It's usually not a problem to have a recessive gene that can cause a defect, unless you procreate with another person that also has the same recessive gene. This can happen with people that aren't related, but is much more likely to occur between two people that come from the same bloodline.
