Karyotype variability in Trypanosoma rangeli
(Cambridge University Press, 1996)
The molecular karyotypes of several different protozoan parasites show high intra-species variation, including different kinetoplastids such as Trypanosoma brucei, Trypanosoma cruzi and Leishmania ssp. In this study, the ...
Karyotype Plasticity in Neotropical Leishmanicr. An Index for Measuring Genomic Distance Among L. (V.) Peruviana and L. (V.) Braziliensis Populations
(Cambridge University Press, 1995)
A method for phenetic analysis of karyotype data has been developed for Leishmania populations. Measurement of size difference between chromosomes recognized by a given DNA probe in different isolates led to the formulation ...
Intrachromosomal karyotype asymmetry in Orchidaceae
(Soc Brasil Genetica, 2017-07-01)
The asymmetry indexes have helped cytotaxonomists to interpret and classify plant karyotypes for species delimitation efforts. However, there is no consensus about the best method to calculate the intrachromosomal asymmetry. ...
Karyotypic characterization of Ramphastidae (Piciformes, Aves)
(Sociedade Brasileira de Genética, 2002-01-01)
The karyotypes of nine species of the family Ramphastidae were determined and compared with that of the toco toucan (Ramphastos toco), the only ramphastid karyotype so far reported in the literature. Differences in the ...

The karyotypes of nine species of the family Ramphastidae were determined and compared with that of the toco toucan (Ramphastos toco), the only ramphastid karyotype so far reported in the literature. Differences in the ...
Molecular karyotype analysis and mapping of housekeeping genes to chromosomes of selected species complexes of Leishmania
(Fundação Oswaldo Cruz. Instituto Oswaldo Cruz., 2019)
First cytogenetic analysis of Ichthyoelephas humeralis (Günther, 1860) by conventional and molecular methods with comments on the karyotypic evolution in Prochilodontidae
(2016-01-01)
We used conventional cytogenetic techniques (Giemsa, C-banding, Ag-NOR), and fluorescent in situ hybridization (FISH) with 5S and 18S rDNA probes to investigate the karyotype and cytogenetic characteristics of Ichthyoelephas ...
Chromosome diversity in species of the genus Arachis, revealed by FISH and CMA/DAPI banding, and inferences about their karyotype differentiation
(Academia Brasileira de Ciencias, 2020-07)
The species of the genus Arachis (Leguminosae) are ordered into nine sections. The assignment of genome types in this genus has been based on cross-compatibility analysis and molecular cytogenetic studies. The latter has ...
