A total of 66 litters were farrowed in a Yorkshire herd of pigs selected for porcine stress syndrome (PSS) susceptibility. These litters included all possible combinations of matings between stress-susceptible, stress-carrier, and stress-resistant animals. When the data were analyzed by within-litter chi-square analysis, the null hypothesis of recessive inheritance could not be rejected (P less than 0.05). In addition, when the data were analyzed across litters, the null hypothesis of autosomal recessive inheritance could not be rejected (P less than 0.05).
在一个因猪应激综合征（PSS）易感性而被挑选的约克夏猪群中，总共分娩了66窝仔猪。这些仔猪包括应激易感、应激携带和应激抗性动物之间所有可能的交配组合。当通过窝内卡方分析对数据进行分析时，隐性遗传的零假设不能被拒绝（P小于0.05）。此外，当对各窝数据进行分析时，常染色体隐性遗传的零假设也不能被拒绝（P小于0.05）。
