查询词典 mating call

Methods The pregnant rats mating in the corresponding period were divided into four groups.As for the Nepionic Rats at the body growth characteristic of different days ages,the method of observing the distance and the relative distance of the anus and the vulvas when they were three to four days old was used to discriminate the sex.When they are five to eight days old,the method of observing the papillas was added to discriminate the sex.

Formation of mating pairs, nicking of the F oriT sequence, and transfer of the 5' end of a single strand of F DNA proceed as in transfer of the F plasmid. Therefore, Part of the plasmid is transferred first, Chromosomal genes are transferred next, and the rest of the plasmid is transferred last.

雌雄菌的交配、F质粒oriT处缺口的形成、以及由单链F DNA5'末端开始转移的过程都与F质粒的转移相同，因此，首先转移的是部分质粒片段，其次是染色体基因，剩余的质粒片段最后被转移。

Seven SSR markers located on seven different chromosomes were utilized in this research, D3Mit22 was selected for detailed analysis.

应用微卫星分子标记对昆明小鼠封闭群相隔10代的两个群体（分别命名为A9和A19）进行遗传背景分析，共设计位于小鼠7条染色体上的7对微卫星引物用于实验研究，选取具有多态性的一个微卫星位点D3Mit22进行详细分析。

Rats were divided into two groups for mating: group one was rendered pangamy and group two was intervened depending on vaginal smear (n=18 for each group).

研究人员说，这是第一次发现单个基因可以同时改变生物的第二性征和择偶偏好。

The index of pleonal expansion (ratio of inter-tergite distances to thoracic length) was significantly different among female reproductive conditions; females with spermatophores just before egg extrusion had the most expanded pleon. In the mating trials, all females showing index values higher than 0.35 mated with males.

腹部宽度指数在雌蟹生殖条件指数具有明显的不同；有精荚的雌蟹在产卵前具有最宽的腹部；在交配实验中，所有与雄蟹交配的雌蟹指数值均高于0.35。
