Cytomixis occurred in meiotic prophase of pollen mother cells ( PMCs ) in the hybrids F 1, which was probably the important reason for aneuploid and multiploid existed in the different populations of I. japonica and I. confusa. 杂种F1减数分裂前期可观察到细胞融合,这可能是造成Ijaponica和Iconfusa不同居群出现多倍体和非整倍体的重要原因。
She was one of seven women who successfully underwent a womb transplant from a live donor – in most cases the recipient's mother - and subsequently had in vitro fertilization ( I V F ) treatment. 她是成功接受来自活人捐赠的子宫移植手术的七名女性之一。大部分捐赠者都是被捐赠人的母亲,然后她们通过检测进行了人工授精。
Cytomixis of pollen mother cells in F1 hybrid of Iris japonica and iris confusa Irisjaponica和Irisconfusa杂种F1花粉母细胞中的细胞融合现象
Meiosis of pollen mother cells was regular in F_1 hybrids. 细胞学观察表明杂种F1的花粉母细胞减数分裂基本正常;
Segregation of the character in four F2 populations tended to its mother, but there were different obviously. F2的分离曲线表现为偏向其母本的分布,但与其母本也有明显差异。
