To date, the panmixia hypothesis has remained unchallenged: genetic studies realized on eel's mitochondrial DNA failed to detect any genetic structure; and a similar lack of structure was found using allozymes, with the exception of clinal variation imposed by selection.

到目前為止，隨機交配假說尚未得到挑戰(zhàn)：通過線粒體研究未發(fā)現(xiàn)鰻鱺存在遺傳結構，而利用同工酶也得到缺乏遺傳結構的相似觀點，而因選擇引起的漸變?nèi)鹤儺愂抢狻?/p>

The observed clinal variation in the frequency of serotinous cones may be described as a fairly regular decrease in all directions.

所觀察到的晚熟球果的頻率梯度變異可描述如下：向四周相當有規(guī)律地漸次減少。

All of these differences appear to be clinal and probably do not warrant taxonomic recognition.

所有這些差別都看起來是漸變的并且或許不保證為分類上的承認A片视频网站在线免费观看。

The clinal variations of at least some physiological characters does not reflect unevnness at the subspecies boundaries.

至少有一些生理性狀的梯度變異反映不出亞種邊界的不齊性。

This simple method gives only an indication of the intensity of selection responsible for the inception and maintenance of clinal variation.

這個簡單方法只能說明對梯度變異開始和保持起決定作用的強度肏屄在线免费视频。
