It is concluded that (1) there are no relationships between fusion rate and relativeness of the recipient cytoplasm to nucleus donor cells,(2) cytoplast of the goat MII oocyte can support the preimplantation development of SCNT embryos reconstructed with nucleus from other species,(3) the blastocyst rate of close relative inter-species SCNT embryos is higher than that of distant relative inter-species SCNT embryos.

由此結(jié)果得出以下結(jié)論：(1)山羊M II期卵母細胞胞質(zhì)與供核細胞之間的親緣性不影響兩者的融合率操人黄片视频免费；(2)山羊M II期卵母細胞的胞質(zhì)能支持異種間體細胞核移植胚的著床前發(fā)育国产一级爱c在线大片；(3)親緣關(guān)系近的種間核移植胚的囊胚發(fā)育率高于親緣關(guān)系遠的種間核移植胚的禁18岁在线永久观看。

Each embryo were inoculated by a dose of 1×104 pure sporozoites was injected with testing Bt crystal proteins before 24 hours. The varying oocyst inhibition rates of embryos brought about by Bt crystal proteins that were given at various doses were used as a criterion for determining the activity of Bt crystal proteins.

Using the Hprt gene as a positive control, our result suggested that both the testis tissue and the male embryos from which Sry transcription can be detected failed to yield any positive results of Xist. Female embryos at the pronucleus stage and 2-cell failed to produce any positive result of Sry and Xist too.

According to the year with the best large-seed production, the reasons for empty seeds could be estimated as follows: Seed potential per cone calculated as 2 times the number of fertile ovuliferous scales was about 206 seeds. Percentages of seed losses resulting from pre-and post-pollination ovule abortion, prezygotic factors, embryo degeneration, and efficient seed were 33%, 27%, 39%, and%, respectively.
