There was also not any haploid metaphases (n=16 or 19) was detected in hybrids. However, about 1-2% metaphases observed in this study was allopolyploid. GISH proved that they was made up of haploid genomes of M. nobilis (n=16) and triploid genomes of C. farreri (n=57). GISH was also employed to detect different chromosome components and identify donor chromatin in hybrids between C. farreri♀×A.

但我们检测到了约1-2%异源多倍体的分裂相，GISH分析后发现这些分裂相是由单倍的华贵栉孔扇贝的染色体和多倍的栉孔扇贝染色体组成，比如论文中图示了一个异源四倍体的分裂相，它是由单倍的华贵栉孔扇贝的染色体(n=16)和三倍的栉孔扇贝染色体(3n=57)组成。

Tetraploid organisms may arise by the fusion of two diploid gametes that have resulted from the nondisjunction of chromosomes at meiosis, or by nondisjunction of the chromoosomes during the mitotic division of a zygote.

四倍体的产生可能是由于两个二倍体配子发生融合，这种二倍体配子又是在减数分裂中染色体不发生分离而形成。四倍体也可能因为受精卵进行有丝分裂时染色单体未发生分离而形成。

It indicated that the yield of tetraploidy not more than 25% induced by inhibiting the first mitosis with CB, colchicine and 6-DMAP, respectively, while it can be induced with higher percentage by blocking PB1releasing with CB. The tetraploidy percentage of groups shock began at 15—22min after fertilization are higher than that shock began at 42min, and the yield of tetraploidy also increased with the CB density and time lasting.

结果表明，CB、6-DMAP和秋水仙素抑制扇贝第一次卵裂诱发四倍体的比例低于25%；采用CB抑制PB1可有效地诱导产生四倍体，从授精后42min提前到15—22min开始处理，抑制PB1的放出有助于提高四倍体的比例，在12℃，处理开始和终止时间分别在授精后20—22min和62—67min时(即PB2始出现时)，面盘幼虫四倍体率最高，为56.5%。

The tetraploids of C.reticulata from the localities with the altitude of over 1800 m were gross-morphologically similar to the hexaploids, but those growing between 1100 ～1800 m were different to some extent from the hexaploids.
