Qualitative and quantitative analysis of the genomes and chromosomes of spider monkeys (Primates: Atelidae)

Heterochromatin distribution and chromosomal rearrangements have been proposed as the main sources of karyotype differences among species of Neotropical primates. This variability suggests that there could be differences at other smaller-scale levels of DNA organization as well. In particular, quant...

We analyzed genome size and its relationship with the presence of chromosomal rearrangements and patterns of heterochromatin distribution. The C-value presented in this work for Ateles chamek is the first estimate for this species (3.09 ± 0.23 pg), whereas our estimates for A. belzebuth (2.88 ± 0.06 pg) and A. geoffroyi (3.19 ± 0.24 pg) differed from those previously published.

description Heterochromatin distribution and chromosomal rearrangements have been proposed as the main sources of karyotype differences among species of Neotropical primates. This variability suggests that there could be differences at other smaller-scale levels of DNA organization as well. In particular, quantitative differences between genomes result from gains and losses of individual DNA segments, and may result in varying genome sizes (C-values) among species. In this work, we studied the genomes of 23 individuals from four species in the genus Ateles (Primates: Platyrrhini): A. chamek, A. paniscus, A. belzebuth, and A. geoffroyi.
