Abstract
Summary
(1) Erythrocyte count, hematocrit determination, hemoglobin content, reticulocyte percentage, total leukocyte count, and proportion of granulocytes were determined in the blood of 2 to 3 month old virgin males and females of 18 different inbred strains. The means and standard errors for each determination are given for each strain. (2) Although there was considerable overlap among the strains, it was possible by analysis of variance to show that there were significant genetic differences among the strains in factors affecting erythrocyte number (as shown both in count and hematocrit), and mean erythrocyte volume (one case only), total leukocyte count, and proportion of granulocytes. (3) Mean total leukocyte count for a strain was negatively correlated with proportion of granulocytes. (4) In this data, the observed strain differences do not appear to be related to differences in other known physiological characteristics.
