Identification of a New Mullet Species Complex Based on an Integrative Molecular and Cytogenetic Investigation of Mugil hospes (Mugilidae: Mugiliformes)
(Frontiers Media Sa, 2018-02-05)
Mullets are very common fishes included in the family Mugilidae, (Mugiliformes), which are characterized by both a remarkably uniform external morphology and internal anatomy. Recently, within this family, different species ...
Microdissection: a tool for bee chromosome studies
(Springer France, 2011-11-01)
The emergence of new molecular biology techniques has provided cytogenetics with tools which allow for the elucidation of questions that classical cytogenetics could not answer. Therefore, the present work standardizes a ...
Chromosomal features of nucleolar dominance in hybrids between the Neotropical fish Leporinus macrocephalus and Leporinus elongatus (Characiformes, Anostomidae)
(Springer, 2009-11-01)
In the present study, the chromosomal mechanisms of nucleolar dominance were analyzed in the hybrid lineage Piaupara, which resulted from crossing the Leporinus macrocephalus female (Piau double dagger u) and L. elongatus ...
Cytogenetics characterization of Crenuchus spilurus (Günther, 1863): a remarkable low diploid value within family Crenuchidae (Characiformes)
(2018-01-01)
Conventional and molecular cytogenetic analyses were performed in specimens of the Neotropical Crenuchus spilurus freshwater fish species from a single location (Caeté River, Brazil). All specimens presented diploid values ...
Comparative cytogenetic study in Muscidae flies
(Instituto Internacional de Ecologia, 2014)
Cytogenetic markers as diagnoses in the identification of the hybrid between Piaucu (Leporinus macrocephalus) and Piapara (Leporinus elongatus)

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 ...
Genomic content and new insights on the origin of the B chromosome of the cichlid fish Astatotilapia latifasciata
(Springer, 2011-10-01)
B chromosomes are additional chromosomes widely studied in a diversity of eukaryotic groups, including fungi, plants and animals, but their origin, evolution and possible functions are not clearly understood. To further ...
Evidence of an XX/XY sex chromosome system in the fish Dormitator maculatus (Teleostei, Eleotrididae)
(Sociedade Brasileira de Genética, 2006-01-01)
The fish Dormitator maculatus has a chromosomes number of 2n = 46, females having a karyotype of 14 M, 28 SM, 2 ST and 2A and males 13 M, 28 SM, 3 ST and 2A. The presence of a heteromorphic pair in the males and a corresponding ...
