Summary
29 imported rams and 26 imported ewes (2 to 4 years old), belonging to the native Russian Romanov breed, and their offspring from two subsequent lambings in 1973 and 1974 were tested for serum albumin types.
Four albumin types (D, F, S and W) have been found, with frequencies of 0.18, 0.16, 0.55 and 0.11, respectively.
AID, being the fastest moving albumin type known, has never been found before, and therefore it is considered as a ‘new’ type.
Available family data support the hypothesis that the synthesis of AID is controlled by a codominant and autosomal allele: AID.
Three variants, A1 S , Al F and Al W, have been described in the albumin system in sheep. A1 S is present in all the breeds studied and the corresponding allele is fixed
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
