Table 3 Ancestral Paenungulata Karyotype (APK) with 2n = 58, XY [2]. APK homologies in representatives of Paenungulata (L. africana – LAF; T. m. latirostris – TML; P. capensis – PCA) and T. inunguis (TIN) data from the present study, considering Orycteropus afer (OAF) and Homo sapiens (HSA) as an outgroup. Chromosome painting data from Pardini et al. [2] and FISH data with TML probes in TIN. The question marks (?) are regions not yet resolved by the chromosomal painting. The abbreviation inv. indicates pericentric inversion and inv/cr indicates in which chromosomes there was inversion/centromeric repositioning

From: Ancestral chromosomal signatures of Paenungulata (Afroteria) reveal the karyotype of Amazonian manatee (Trichechus inunguis, Sirenia: Trichechidae) as the oldest among American manatees
