Abstract: | Karyological characterizations of C. s. utahicki (2n = 54) and C. s. chiropotes (2n = 54) showed that these two subspecies are chromosomally very similar. In a single, isolated specimen of C s. utahicki, however, a derived, biarmed, chromosome 14 was found in the heterozygous condition. This variant chromosome was identical with pair 10 in C. s. chiropotes in which this chromosome type was apparently fixed. Chromosome differences between these subspecies might be transitional, leading to the establishment of two different karyomorphic populations derived from a once uniform karyotypic group that split into separate allopatric subspecies. © 1992 Wiley-Liss, Inc. |
