Thiamin deposition in eggs is not dependent on riboflavin-binding protein.
The thiamin content of eggs laid by hens possessing no, one or two functional genes for riboflavin-binding protein is unaffected by the genotype. This does not support the hypothesis of Muniyappa & Adiga [Biochem. J. (1979) 177, 887-894] that the deposition of thiamin-binding protein is coupled to the deposition of riboflavin-binding protein.
