【摘要】 在二倍体与四倍体杂交产生的三倍体牡蛎群中检测到了非整倍体 ,其中 3n± 1非整倍体相对于三倍体的存活率为 6 0 .98%。非整倍体牡蛎作为一个群体 ,其生长与其三倍体同胞在体重上无明显差异 ,且与三倍体一样明显大于其二倍体对照组。非整倍体牡蛎的性腺发育情况与三倍体个体相当 ,也能产生成熟的生殖细胞更多还原

【Abstract】 Aneuploid Pacific oyster were founded in triploid population produced by mating diploid with tetaploid oyster. The survival rate of 3n±1 aneupploids was 60.98% relative to that of triploids. Aneuploids as a group did not differ significantly in body weight from their triploid counterparts. The gonadal development in aneuploid is similar to that of triploids and can produce mature gametes.更多还原
