Statistically speaking, a variety of genetic disorders that may not even come fully to term.
Theres actually something floating around somewhere that goes through the biology of people with identical genomes aside from the sex chromosomes breeding. Its equivilent to roughly 4 straight generations of sibling incest if i remember correctly.
With this type of futa, I've always wondered - what would happen if they were to put their own cum in their vagina?
Medically speaking, it wouldn't happen. There have been no recorded cases of intersex (a more general and medically accepted term for "futas") humans actually having both working sets of genitalia.
In species that do have true hermaphrodites (a term medically discouraged from being used on humans, as humans don't exhibit true hermaphrodism), there is nearly always a mechanism preventing self-fertilization in nature.
It's only in crop plants selectively bred for thousands of years that you can really find self-fertilizing hermaphrodite species, since that means that you can take the wheat stalks that produce the most grain and breed them with itself to help selectively breed the best crops for the next harvest.
As Blockhead says it, though, if you did manage to somehow impregnate yourself (or a clone of yourself), it would have four times the inbreeding coefficient as a sibling pregnancy (since standard siblings only share 25% of their DNA). (The child would be like a clone of yourself with only 3/4ths of your genes. Think of those Punnett Squares where hair color is determined by whether things are capitalized, like BB, Bb, or bb. If you had Bb hair color genes, and then mated with yourself/your clone, the child has a 50% chance of having BB or bb hair, functionally losing the genetic diversity of that other gene.) There's actually a chapter on this in (XCKD's author) Randall Munroe's book "What If" (but not available online...)
