查询词典 gametes

The hybrid between Brachymystax lenok and Hueho taimen were not a live in the past 2 years. However, the fertility and eyed rate of BH were significantly higher than that of HH and BB (P.05), while the hatching rate were significantly lower (P.05). The larvae died within 1 to 2 hours after hatching. It was observed that the tail of yolk-sac larve couldn't stretch around the yolk, and there were hyperemia in the middle and posterior segment of the tail. The reason why the hybrid between Brachymystax lenok and Hucho taimen couldn't snrvive might was the karyoplasms of the gametes from Brachymystax lerwk and Hucho taimen by distant hybridization were not compatible.

细鳞鲤×哲罗鱿的杂交经过2年多批次实验均未得到成活杂交子代，但在胚胎发育阶段BH的杂交受精率、发眼率均显著高于双亲自繁对照组(P.05)，但其孵化率显著低于双亲对照组(P.05)，BH杂交子代在破膜后1~2h内即死亡，刚破膜的仔鱼尾干中后段至尾鳍部分盘绕于卵黄囊表面不能伸展，且所有破膜仔鱼的尾干中后段均存在充血点，本研究认为，这种反交［细鳞鲑×哲罗鲑］子代不能成活的原因可能是由远缘杂交受精卵核质不相容所导致。
