The distribution of 45s rDNA sites in bird chromosomes suggests multiple evolutionary histories
(Sociedade Brasileira de Genética, 2020)
The distribution of 45S rDNA cluster in avian karyotypes varies in different aspects, such as position, number of
bearer chromosomes, and bearers being macro- or microchromosomes. The present study investigated the ...
Comparative analyses of three swallow species (Aves, passeriformes, hirundinidae): insights on karyotype evolution and genomic organization
(Sociedade Brasileira de Genética, 2020)
Despite the richness of species in the Hirudinidae family, little is known about the genome organization of swallows.
The Progne tapera species presents genetic and morphological difference when compared to other members ...
