Chimaera (redirected from Ghost shark)

Chimera

Any individual or molecule derived from 2 or more species
Embryology An individual that results when an embryonic part of one animal is grafted onto another, or a part from an animal is grafted onto another body
Genetics An organism with 2 or more cell lines, genotypes, or karyotypes descended from at least 2 zygotes—a very rare phenomenon seen only in twins, resulting from chorionic vascular anastomoses, transplantation, or double fertilization, and subsequent participation of both fertilized meiotic products in one developing embryo; all hermaphrodites should be karyotyped to evaluate possible chimerism
Transplantation The term chimera was also once used for a person who had received transplanted tissue—e.g., bone marrow—that survived in the recipient
