Two lines of Japanese quail were divergently selected for high and low antibody responses after being twice injected at 4 and 6 weeks of age with inactivated Newcastle disease virus antigen. After seven generations of selection, the serum antibody level in the high line was 24% greater than the level in the unselected control lines, whereas the low line antibody level was approximately 37% less than that in the control line. The estimated heritability (H2S + D) was approximately .12 +/- .50. The realized h2, calculated from coefficient of regression formula on seven generations (G3 to G9 ), was .07.
对两行日本鹌鹑进行了不同方向的选择，在4周龄和6周龄时两次注射灭活新城疫病毒抗原后，分别选择抗体反应高的和低的。经过七代选择后，高反应品系的血清抗体水平比未选择的对照品系高24%，而低反应品系的抗体水平比对照品系低约37%。估计的遗传力（H2S + D）约为0.12±0.50。根据七代（G3至G9）的回归系数公式计算得到的实际遗传力h2为0.07。
