In two equal periods, using the conventional method of processing bone-marrow cells after Konstantinov and Dobriyanov (1974), we studied the connection between the occurrence of chromosomal aberrations and deviations of phenotype. In the first part of the observation we found 8.5% numerical aberrations in 20 ducklings with retarded motility, torticollis and contractures of the fingers, compared with 1.27% in the control group with normal phenotype. In the second part of the observation the occurrence of aberrations in ducklings with defective phenotype of the same breeding dropped considerably to 1.7% and in the control group to 0.54%. The statistical evaluation of the results showed statistically significant differences (chi (4)2 = 56.78; p less than 0.05, and/or chi (4)2 = 27.74; p less than 0.05).
在两个相等的时间段内，我们采用康斯坦丁诺夫和多布里亚诺夫（1974年）之后的传统方法处理骨髓细胞，研究了染色体畸变的发生与表型偏差之间的联系。在观察的第一部分中，我们发现20只运动迟缓、斜颈和手指挛缩的小鸭中有8.5%出现了数值畸变，而表型正常的对照组中这一比例为1.27%。在观察的第二部分中，同一品种有缺陷表型的小鸭中畸变的发生率大幅下降至1.7%，对照组则降至0.54%。结果的统计评估显示出具有统计学意义的差异（卡方(4)2 = 56.78；p < 0.05，和/或卡方(4)2 = 27.74；p < 0.05）。
