This is not a Jerry Springer headline -- despite all the sizzling, implicit drama involved -- heteropaternal superfecundation is a fertilization term when a woman is successfully impregnated by different/multiple men in the same ovulation cycle.
We all know that kitten and puppies from the same litter can be fathered by multiple males (yay for a variety of breeds!)... And we don't typically associate human pregnancies in the same boat because... to be fair... this is quite rare. But how rare is it? Statistics?
- So the infants are fraternal twins AND half-siblings? Is there a term that comprises this relationship.
- What is the history behind identifying this fertilization process? When was it officially documented? Did they have any suspicions before DNA (like if children born different races)?
