First Description of a Satellite DNA in Manatees' Centromeric Regions.

and are the two Sirenia species that occur in the Americas. Despite their increasing extinction risk, many aspects of their biology remain understudied, including the repetitive DNA fraction of their genomes. Here we used the sequenced genome of and TAREAN to identify satellite DNAs (satDNAs) in this species.

Chromosome Painting in Callicebus nigrifrons Provides Insights into the Genome Evolution of Titi Monkeys and the Ancestral Callicebinae Karyotype.

We studied the chromosomes of Callicebus nigrifrons with conventional and molecular cytogenetic methods. Our chromosome painting analysis in C. nigrifrons together with previous reports allowed us to hypothesize an ancestral Callicebinae karyotype with 2n = 48.
