- Unreduced gametes are common in plants and likely represent the most frequent route to polyploidy . 在植物中未减数配子非常普遍,他们可能代表了多倍体形成的最普遍的方式。
- Polyploids can arise by somatic doubling, by the fusion of unreduced gametes, and by means of a triploid bridge. 多倍体产生与体细胞染色体的加倍、未减数配子的融合以及一种叫三倍体桥的方法。
- The major cytological mechanisms of polyploid formation are union of unreduced gametes, somatic doubling and polyspermy.And union of unreduced gametes is the most important mechanism. 多倍体主要是通过未减数配子融合,体细胞染色体加倍以及多精受精三种方式起源的。
- Lots of incompletely duplicative or dificient unreduced gametes were produced from loses or nondisjuction of chromosomes.The frequency of the completely unreduced gamete was very low. 由于染色(单)体的丢失或不分离可产生大量的不完整的重复、缺失未减数配子,完整未减数配的频率很低。
