Abstract
Species specificity of commercial human DNA quantification kits and short tandem repeat (STR) profiling kits was examined using primate DNA samples. These samples comprised 33 individuals from eight primate species, each with gender and kinship data, including human (Homo sapiens), chimpanzee (Pan troglodytes), gorilla (Gorilla gorilla), and orangutan (Pongo pygmaeus) of Hominidae family, and Japanese macaque (Macaca fuscata), long-tailed macaque (Macaca fascicularis), hamadryas baboon (Papio hamadryas), and savannah monkey (Chlorocebus sp.) of Cercopithecidae family. The findings revealed varying levels of cross-species amplifications in all non-human DNA samples that correlated with their evolutionary proximity to humans, both kit types. Moreover, cross-species amplification, including female DNA samples, was observed in a Y-chromosomal STR profiling kit. Additionally, species specificity differed among the commercial kits examined. The cross-species amplification data presented in this study offer valuable assistance in interpreting the results of individual human identification in forensic cases involving non-human primates.

Amplification Dynamics of Platy-1 Retrotransposons in the Cebidae Platyrrhine Lineage. Genome Biol Evol 2019; 11:1105-1116.

Abstract
Platy-1 elements are Platyrrhine-specific, short interspersed elements originally discovered in the Callithrix jacchus (common marmoset) genome. To date, only the marmoset genome has been analyzed for Platy-1 repeat content. Here, we report full-length Platy-1 insertions in other New World monkey (NWM) genomes (Saimiri boliviensis, squirrel monkey; Cebus imitator, capuchin monkey; and Aotus nancymaae, owl monkey) and analyze the amplification dynamics of lineage-specific Platy-1 insertions. A relatively small number of full-length and lineage-specific Platy-1 elements were found in the squirrel, capuchin, and owl monkey genomes compared with the marmoset genome. In addition, only a few older Platy-1 subfamilies were recovered in this study, with no Platy-1 subfamilies younger than Platy-1-6. By contrast, 62 Platy-1 subfamilies were discovered in the marmoset genome. All of the lineage-specific insertions found in the squirrel and capuchin monkeys were fixed present. However, ∼15% of the lineage-specific Platy-1 loci in Aotus were polymorphic for insertion presence/absence. In addition, two new Platy-1 subfamilies were identified in the owl monkey genome with low nucleotide divergences compared with their respective consensus sequences, suggesting minimal ongoing retrotransposition in the Aotus genus and no current activity in the Saimiri, Cebus, and Sapajus genera. These comparative analyses highlight the finding that the high number of Platy-1 elements discovered in the marmoset genome is an exception among NWM analyzed thus far, rather than the rule. Future studies are needed to expand upon our knowledge of Platy-1 amplification in other NWM genomes.
