'''Heteropaternal superfecundation''' is a rarely occurring [[medical]] term describing the [[fertilization]] of two or more [[ovary]] by [[sperm]] from different males. According to Academic Dictionaries & Encyclopedias, "A woman who has sexual relations with two or more men at short intervals within the same ovulatory period can be impregnated by both men," thus twin newborn children are half-brothers or half-sisters with different [[father]]s. Among some animal species, however, it is quite common(such as cats). <ref>[http://dic.academic.ru/dic.nsf/enwiki/1095474 Heteropaternal superfecundation] Academic Dictionaries & Encyclopedias</ref>
