Abstract
An examination of the karyotypes of female homozygous normals, homozygous dwarfs of the 'snorter' type, and heterozygotes in Hereford cattle, using the leucocyte culturing technique, revealed no differences between the three. The karyotypes of an unclassified group of phenotypically normal males were similar except for the male determining chromosome. The latter was clearly shown in the karyotypes to be of the submetacentric X type and about [Formula: see text] the size of the larger X type chromosomes.
