| [comparative cytogenetics of three species of south american field hamsters of the genus akodon (rodentia, cricetidae)]. | a karyological analysis of three species of south american field mice of the genus akodon from four different localities of the department of tarija, bolivian republic, was performed. in akodon simulator, 2n = 40 - 42, nfa = 42. the variation of the diploid number is caused by a polymorphism of the robertsonian type involving six pairs of acrocentric chromosomes. five variants of karyotypes were revealed. the chromosome set of a. sp. has 2n = 36, nfa = 40; in a. toba, 2n = 42 - 43, nfa = 44 - 46 ... | 1996 | 8647427 |
