The fecundity of an F1 male hybrid deer, from a cross between a male Odocoileus virginianus (white-tailed deer) and a female O. hemionus (mule deer), was assessed by cytogenetic and flow cytometric techniques. Analysis of chromosome morphology, nucleolus organizer expression, meiotic chromosome pairing, sperm production, and nuclear gene inheritance revealed no genetic anomalies that could potentially impair normal fertility. These observations are discussed in relation to recent reports of hybridization between natural populations of these two species.
通过细胞遗传学和流式细胞术技术评估了一只雄性F1杂交鹿的繁殖力，该杂交鹿由一只雄性弗吉尼亚鹿（白尾鹿）与一只雌性黑尾鹿杂交产生。对染色体形态、核仁组织区表达、减数分裂染色体配对、精子产生和核基因遗传的分析表明，不存在可能损害正常生育能力的遗传异常。结合最近关于这两个物种自然种群之间杂交的报道对这些观察结果进行了讨论。
