粗线期染色体荧光原位杂交结果表明，大多数染色体的末端都有端粒串联重复，但信号的强度在不同染色体上是不同的。
Pachytene FISH results showed that most of chromosome ends possess the telomere tandem repeats, but the signals on different chromosomes were not the same in intensity.
前期可被分为连续的阶段：细线期、偶线期、粗线期、双线期和终变期。
Prophase may be divided into successive stages termed leptotene, zygotene, pachytene, diplotene, and diakinesis.
第二，改变普遍采用的粗线期染色体制备的传统方法，尝试用酶解滴片法制备了水稻减数分裂染色体，获得了成功。
Second, it is successful to try applying the dripping method of suspended cells obtained by enzyme treatment instead of traditional method for pachytene chromosomes preparation.
