A case of bovine embryonic duplication is described. The genetic sex of each of the conjoined twin calves was determined mainly as a result of ambiguity in the phenotypic sex of one of the twins. Chromosome analysis was based on fibroblast cultures initiated from skin tissue. Although genetically isosexual and therefore indicative of monozygosity, an alternative origin for isosexual twinning is highlighted. The probable etiology of the conjoined twinning is discussed.
描述了一例牛胚胎复制的病例。连体双胎小牛中每一头的遗传性别主要是由于其中一头双胎的表型性别存在模糊性而确定的。染色体分析基于从皮肤组织开始的成纤维细胞培养。尽管在基因上是同性别的，因此表明是单合子性，但同性双胎的另一种起源也被强调。讨论了连体双胎的可能病因。
