Abstract:Abstract. The aim of this study was to analyze the genetic
structure of the casein cluster in eight selection lines of the
Holstein Friesian (HF), German Simmental (GS) and German Black Pied cattle
(“Deutsches Schwarzbuntes Niederungsrind”, DSN) breeds.
A total of 2962 milk
samples were typed at αs1-casein (αs1-CN),
β-casein (β-CN), αs2-casein (αs2-CN) and κ-casein (κ-CN) loci using isoelectric
focusing. The number of alleles per locus ranged from one (αs2-CN) to five (β-CN), and the average expected
heterozyg… Show more
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.
