The haemoglobin types of mice.

The haemoglobin types of 27 inbred strains of mice have been determined. Besides the common types, Hbb-s and Hbb-p, 2 strains were found with Hbb-p. Affinity between strains with the Hbb-p type and asiatic mice seems likely. The influence of storage on the polymerisation of Hbb-d and Hbb-p, the possibility of distinguishing between homo- and heterozygote Hbb types, and the possible existence of a 4th haemoglobin type, are discussed.
