Hi! Chimerism represents the presence of 2 or more genetically different cell lines(derived from 2 zygotes) in an individual.Note:Try not to mix term with mosaicism where individual consist of 2 or more cell lines derived from a single zygot(same genetic origin). In humans 2 kinds of chimeras exist:
Dispermic(result of double fertilization and then fusion of 2 zygotes-hermaphroditism can develop if 2 zygotes are of different sex).
Blood chimeras-result of exchange of cells between non-identical twins in utero(via placenta).
