一例母及其亲子DNA指纹与血清蛋白、酯酶遗传的研究

A Genetical Study on DNA Fingerprints, Serum Protein and Esterase Contents in a Case of Female Hinny and Her Offspring

采用ＤＮＡ指纹分析和聚丙烯酰胺凝胶电泳法，对一例与公驴交配生育了后代的母后代进行了亲缘鉴定和血清蛋白、酯酶遗传的分析。结果可以认定其亲子关系并证实母骡生育的事实。虽然本例母的后代在Ｐｒ、Ａｌ、Ｐａ和Ｈｂ、Ｅｓ等基因座位上的基因表达倾向于驴，但其外貌仍明显地带有种间杂种的特征。因此，尚不能简单地认为其已“回归”为纯种的驴。

By adopting DNA fingerprints analysis and polyacrylamidegel electrophoresis simultaneously, the author made an genetical study on analytical evaluation of kindred relationship and contents of serum protein and esterase of a female hinny and her offspring bred after her mating with a masculine ass. As a result, the parental relationship together with the child-bearing fact of the hinny is hereby clearly verified. The appearance of the offsping, however, still showed some prominent characters of interspecific hybrid, though in the gene demonstration the offsping was proved inclining to the ass especially on those gene loci as Pr, AL, Pa, Hb, and Es . Therefore, in the author's opinion, the offsping could not be simply regarded as a “regressed” ass pure-line.
