本文提供了十足目染色体情况的检索表(截止到1987年),并编排为计算机检索数据库.26个科的68种十足目动物的二倍体染色体数目从64到376不等(平均125).由于染色体太小(不超过4μm),所以关于染色体形态学和其他细胞核学方面的资料很少.性染色体只在铠甲虾科中的1个种和方蟹科中的7个种中有过报道.关于染色体数目和DNA含量的研究结果,还不足以确定以前提出的关于虾类的系统发生过程中存在倍数性进化的观点.
In this article, a list of ten chromosomes (up to 1987) is provided and compiled into a computerized searchable database. The 68 species of decathletes in 26 families have diploid chromosome numbers ranging from 64 to 376 (average 125). Because chromosomes are too small (less than 4 μm), there is very little information on chromosomal morphology and other cytogenetics. Sex chromosomes have been reported in only one of the armor shrimp families and seven of the family Crabs The results of studies on the number of chromosomes and DNA content are not enough to determine the previously proposed concept of multiple evolution in the phylogenetic tree of shrimp.
