Possible origin of B chromosome in Dichotomius sericeus (Coleoptera)
(Canadian Science Publishing, Nrc Research Press, 2016-08-01)
B chromosomes have so far been described in about 80 species of Coleoptera, mainly using conventional staining analysis. In this study, 152 individuals of the dung beetle Dichotomius sericeus (Coleoptera), collected from ...
Characteristics of NOR-banded chromosomes of Mangalarga horses
(1990-10-02)
The nucleolar organizer regions (NORs) of Mangalarga horses were characterized by analysis of NOR-banded metaphase chromosomes according to the technique of Goodpasture and Bloom (Chromosoma 53: 37-50, 1975). NOR banding ...

Dipteran chromosomes: a simple method for obtaining high quality chromosomal preparations
(Indian Academy of Sciences, 2014-12)
For cytogenetic studies it is necessary to develop an efficient method of chromosome preparation with wellpreserved and dispersed chromosomes and little or no cell-wall debris. In this study, we describe a method for ...
Interstitial long-arm deletion of chromosome 7 and ectrodactyly
(1989-01-01)
An interstitial deletion of 7q21 was found in a boy with mental retardation, microcephaly, convergent strabismus, micrognathia, genital anomalies, and other findings, including ectrodactyly.

The Y Chromosome of the Atelidae Family (Platyrrhini): Study by Chromosome Microdissection
(KARGER, 2009)
In order to study the intergeneric variability of the Y chromosome, we describe the hybridization of the Y chromosome of Brachyteles arachnoides, obtained by microdissection, to metaphases of Ateles belzebuth marginatus, ...
Translocation (4;14) and concomitant inv(14) in a basal cell carcinoma
(1991-12-01)
Chromosome analysis of short-term cultures from a basal cell carcinoma was performed. The analyzed karyotypes showed a pseudodiploid clone characterized by a der(4)t(4;14)(p14;p11) and a concomitant inversion of the same ...
