- maxerickson 10y agoThat's not true. Most genetic disorders are caused by receiving one or more defective copies of a gene. In the case of a single defective gene causing the disorder, it doesn't make a difference what gene the other parent has. In the case where multiple defective copies cause the disorder, the further apart two lineages are, the less likely it becomes that they will each have defective copies of the same gene. There's probably a higher chance of blood type incompatibilities, but that isn't a lifetime genetic disorder for the child, it just needs to be accounted for during the pregnancy.
