Chromosomal differentiation of populations of Lysapsus limellus limellus, L. l. bolivianus, and of Lysapsus caraya (Hylinae, Hylidae)
(Elsevier B.V., 2006-01-01)
Cytogenetic analysis were done on specimens from two populations of Lysapsus limellus limellus. three of L. l. bolivianus and of one of Lysapsus caraya. All animals showed a diploid chromosomal number of 2n=24. The karyotypes ...
Molecular cytogenetic analysis of heterochromatin in the chromosomes of tilapia, Oreochromis niloticus (Teleostei : Cichlidae)
(Kluwer Academic Publ, 1998-04-01)
The structure of the heterochromatic bands in mitotic chromosomes of the important tropical aquaculture species of tilapia, Oreochromis niloticus, was investigated by the combination of the C-banding technique, chromosomal ...
Distribution of constitutive heterochromatin in species of triatomines with fragmentation of sex chromosomes X
(2014)
Cytogenetic analyses of triatomines are considered to be important taxonomic tools. Thus, we analyzed the pattern of constitutive heterochromatin in 7 species of triatomine with fragmentation of the sex chromosome X, ...
Cytogenetic analysis of four species of Pseudis (Anura, Hylidae), with the description of ZZ/ZW sex chromosomes in P. tocantins
(SpringerDordrechtHolanda, 2008)
Differentiation of Nolana and Sclerophylax (Solanaceae) by means of heterochromatin and rDNA patterns
(Taylor & Francis, 2017-01-05)
Within Solanaceae, Nolana L. f. and Sclerophylax Miers are two genera that have deserved special attention because of their rare anatomical characteristics. However, they are poorly known from the cytogenetic perspective. ...
Comparative Cytogenetic Analysis of the Genus Symphysodon (Discus Fishes, Cichlidae): Chromosomal Characteristics of Retrotransposons and Minor Ribosomal DNA
(Karger, 2009-01-01)
As part of a genetic screening program for wild Discus fishes, we analyzed karyotypes and cytogenetic characteristics of Symphysodon aequifasciatus, S. discus and S. haraldi using C-banding and fluorescent in situ hybridization ...
