Gel Image of Polymorphic Locus 35154 (JH378108:33053451–33054957). This image displays a polymorphic locus in the Saimiri genome [saiBol1]. Lanes: 1- 100 bp ladder, 2- TLE (Negative control), 3- Human (HeLa), 4-Callithrix jacchus (Common marmoset), 5–16 Saimiri sciureus (Common squirrel monkey), 17–32 Saimiri boliviensis (Bolivian squirrel monkey), 33–35 Saimiri boliviensis peruviensis (Peruvian squirrel monkey), 36- Saimiri oerstedii oerstedii (Panamanian red back squirrel monkey), 37- Saimiri sciureus macrodon, 38-Saimiri sp. The presence of the Alu element is indicated by the ~ 655 bp band and the absence by the ~ 346 bp band. Species with multiple individuals are grouped together by colored brackets (Orange- Common squirrel monkey, Blue- Bolivian squirrel monkey, Green-Peruvian squirrel monkey). Lanes 7(UWBM# 75531) and 12(MVZ Mamm 193661) share an insertion with the Bolivian squirrel monkeys whom are either homozygous present or heterozygous for the insertion (lanes 17–32). Lane 38 (species unknown) is heterozygous for the insertion
