[00:31.589] | 在同源染色体上的等位基因分离 |
[00:34.739] | 非同源染色体上的符合自由组合定律 |
[00:39.289] | 你数染色体要数几个着丝粒 |
[00:42.289] | 姐妹染色单体分开就不能再叫单体 |
[00:46.339] | 间期前Ⅰ中Ⅰ联会在哪个时期(在前Ⅰ这里开始) |
[00:50.989] | 每个四分体有几个染色体和单体(1个四分体=一对同源染色体=2条染色体=4条染色单体) |
[00:55.693] | 经过了整个中期Ⅰ联会的同源染色体 |
[00:57.996] | 在赤道板的两侧排列整齐 |
[01:01.596] | 当染色体被纺锤丝拉向两极 |
[01:08.401] | 后Ⅰ就开始自由组合和分离 |
[01:14.201] | 染色单体在S 期出现前期核膜跟核仁消失不见 |
[01:22.760] | 第四个时期后缩短螺旋形态大小中期依然清晰可见 |
[01:31.111] | 后期染色单体消失不见变成两条染色体分向两边 |
[01:37.911] | 分裂前后染色体数不变那是有丝分裂的特点周期会重演 |
[01:47.812] | 减数分裂末期Ⅰ同源染色体已分离 |
[01:54.662] | 细胞在前Ⅱ时期分到两个次级里面 |
[01:58.364] | 精母数会均等分离卵母产生第一极体 |
[02:02.414] | 所以雌(♀)配子是雄(♂)的四分之一 |
[02:05.914] | 当图文里只剩下奇数染色体 |
[02:11.615] | 周期就成了减数第二次前期 |
[02:22.204] | 我给你的爱写在中Ⅱ里赤道板上排着一行着丝粒 |
[02:27.104] | 其实后Ⅱ很像有丝后期区别是前者没有同源染色体 |
[02:35.09] | 我给你分析减二的末期相同的配子来自同个次级 |
[02:42.213] | 互补配子来自同个初级减数分裂两次只复制一次 |
[02:52.156] | 我感到很疲倦那么多的知识点 |
[02:58.816] | 害怕记不住关键是没时间 |
[03:03.316] | 萨顿说染色体理论之前孟德尔还在用豌豆做实验 |
[03:12.470] | 摩尔根用果蝇实验发现染色体上基因竟然清晰可见 |
[03:20.571] | 减数分裂发生在受精前所以两代间染色体数不变 |
[03:27.623] | 用基因文字刻下了永远那一份大前年的试卷一年年重演 |
[03:37.378] | 别在考试前才在花时间 |
