Samples of whole blood of a Boergoat buck (60,XY), and ewe (54,XX) and her heterosexual twins were cytogenetically examined. The female offspring had hair and seemed to be a cross between the two animals. However, both twins possessed 54 chromosomes, including 6 large submetacentric autosomes, whose R- and G-banding patterns were identical to those of the ewe.
对一只波尔山羊公羊（60，XY）、一只母羊（54，XX）及其异性双胞胎的全血样本进行了细胞遗传学检查。雌性后代有毛发，似乎是这两种动物的杂交后代。然而，这对双胞胎都有54条染色体，包括6条大型亚中着丝粒常染色体，其R带和G带模式与母羊的相同。
