Blood characters, such as, erythrocyte number, leukocyte number, hemoglobin content, serum protein percentage, leukocyte diagnosis and liver dehydrogenase activity were determined among the W1 and W2 subline and their reciprocal hybrids, W1 (_??_) ×W2 ( _??_) and W2 (_??_) ×W1 ( _??_) .
There were significant genetic differences among the two lines and hybrids in factors affecting erythrocyte number, leukocyte number and hemoglobin content. Erythrocyte number was 867 in W1, 777 in W2, 878 in W1×W2 and 786 in W2×W1 (ten thousand) . Leukocyte number was 5, 871 in W1, 7, 750 in W2, 6, 356 in W1×W2 and 7, 242 in W2×W1. Hemoglobin content was 16.49 in W1, 16.06 in W2, 16.40 in W1×W2 and 15.10 in W2×W1 (g/dl) . The values of erythrocyte number, leukocyte number and hemoglobin content in F1 from mother showing high values were higher as compared with those in F1 from mother showing low values. The results might indicate that there are certain maternal effects for the blood characters of hybrids mice.
Intensity of heterosis was concluded by the calculation of potence ratio in F1 with the following results. Erythrocyte number, showed higher value in W1×W2 than in W1, W2, showing intense heterosis, and hemoglobin content lower value in W2×W1 than in W1, W2. Other characters in F1 showed intermediate value of W1 and W2.
