A New Series of Allelomorphs in Mice

Article metrics


THERE appeared recently 1 a paper by P. J. Cammidge and H. A. H. Howard on “The Hereditary Transmission of Hypoglycæmia in Mice” which contains facts of considerable interest to students of genetics. These authors had previously shown that the condition of high blood sugar in mice (hyperglycæmia with blood sugar values of 110–125 mgm. per 100 c.c. of blood) behaves as a simple recessive to the normal condition (about 80 mgm.).2 They have now found mice with very low blood sugar value (about 60 mgm.), and this condition also behaves as a simple recessive to the normal. Segregation in both cases is clear, no intermediate values having been found.
