When they analyzed DNA to determine its relationship to others, they were stunned to find that it was a hybrid of two closely related flies, the blueberry maggot and the snowberry maggot.
Being simple and rapid, two methods could reduce the cost and make extraction of DNA very easily; thus they were suitable for the purity identification of Cucumber hybrid seeds.
这两种方法不仅节约成本，且简单快速，大大降低了DNA的提取难度，适宜黄瓜杂交种子纯度鉴定。

The pairings created viable hybrid offspring—identified by their DNA and skulls—that have been found in mid-Atlantic states such as New York and Pennsylvania.
