Technically, inbreeding doesn’t cause genetic disorders. What inbreeding in fact does is 1) restrict variation in the gene pool and 2) increase the likelihood of recessive alleles being expressed.
There are two types of genes: dominant and recessive. Dominant genes always actually affect your body. Recessive ones only show up if you receive them from both parents.
That being said you definitely have a ton of recessive genes that have no effect on your body because you only relieved them from one parent. Furthermore, your genes mutate, and those mutations either show up or they don’t. As such, you likely have some weird mutated genes that would be really bad if they were dominant, but they aren’t.
