Abstract
ALTHOUGH it is known that many cases of naturally occurring bi-paternal litters are probably born each year in domestic sheep flocks no well-authenticated examples seem to have been reported. Certainly none seems to have been studied in any detail when they have been seen. Apart from its value as an established case of this phenomenon, the present example is unusual in the wide diversity of the genotypes involved and the small but significant array of characters it has been possible to observe in this very mixed family group.
