The Callitrichidae are family of small New World primates with a suite of distinctive morphological and behavioral adaptations that set them apart from other primates. Of primary interest is their reproductive system that includes compulsive twinning: ≥80% of births) and cooperative care of offspring by individuals other than biological parents: termed alloparenting). Further, hematopoietic tissues in callitrichids display signals of both self and sibling DNA, due to an exchange of stem cells early in gestation that renders twin callitrichids as cellular mosaics of each other. This phenomenon is known as genetic chimerism, which increases genetic relatedness between individuals and is …
