The complex genetic examination of hedgehogs from the vicinity of the village of Nikolina Gora (Moscow region, Odintsovskii district) showed both Erinaceus europaeus and E. roumanicus in the sample. One of the hedgehogs was designated as E. roumanicus by the nucleotide sequence of 1 TTR intron but possessed mitochondrial DNA of E. europeus. Only one of the chromosomal pairs that differ in E. europeus and E. roumanicus was heteromorphic in this specimen. Its hybridous origin as the offspring of one or several back-crosses between F1 hybrid and E. roumanicus was suggested.
对来自尼科利纳·戈拉村（莫斯科州奥金佐夫斯基区）附近的刺猬进行的复杂基因检测显示，样本中既有西欧刺猬，也有罗马尼亚刺猬。其中一只刺猬根据1个甲状腺素运载蛋白（TTR）内含子的核苷酸序列被认定为罗马尼亚刺猬，但它拥有的是西欧刺猬的线粒体DNA。在这个样本中，西欧刺猬和罗马尼亚刺猬之间存在差异的染色体对中只有一对是异形的。有人提出它具有杂种起源，是F1杂种与罗马尼亚刺猬一次或多次回交的后代。
