In this work we present a new karyotype for Rhipidomys Tschudi, 1845 (Cricetidae, Rodentia) from Brazil. Our chromosome analyses included GTG- and CBG-banding patterns, the localization of the nucleolus organizer regions after silver staining (Ag-NORs) and fluorescence in situ hybridization (FISH) with a telomere probe. The new karyotype is composed of 44 chromosomes and has a fundamental numbe...

Mus terricolor chromosomal types I, II, III from different places of India were cytogenetically analyzed. Chromosome types II and III showed polymorphic pericentric inversions of autosomes 2 and 5 present in homozygous or heterozygous condition in the populations. Moreover, besides fixed heterochromatic arms on autosomes 1, 3, and 6; the autosome 8 in terricolor type III showed a large heteroch...

Six populations of Sinipta dalmani from the provinces of Buenos Aires and Entre Rios (Argentina) were analyzed. The populations of “El Palmar” National Park (Entre Rios) were polymorphic for pericentric inversions in pairs M4 and M7 and for a centric fusion involving pair M5 and the X chromosome. The M4 inversion remained similar over time and the karyomorphic frequencies did not depart from th...

Centromere positions on 7 maize chromosomes were compared on the basis of data from 4 to 6 mapping techniques per chromosome. Centromere positions were first located relative to molecular markers by means of radiation hybrid lines and centric fission lines recovered from oat-maize chromosome addition lines. These centromere positions were then compared with new data from centric fission lines r...

Two unrelated mildly retarded males with inversions of the X chromosome and non-specific mental retardation (MRX) are described. Case 1 has a pericentric inversion 46,Y,inv(X) (p11.1q13.1) and case 2 a paracentric inversion 46,Y,inv(X) (q13.1q28). Both male patients have severe learning difficulties. The same chromosomal abnormalities were found in their mothers who are intellectually normal. F...

Turdus rufiventris and Turdus albicollis, two songbirds belonging to the family Turdidae (Aves, Passeriformes) were studied by C-banding, 18S rDNA, as well as the use of whole chromosome probes derived from Gallus gallus (GGA) and Leucopternis albicollis (LAL). They showed very similar karyotypes, with 2n = 78 and the same pattern of distribution of heterochromatic blocks and hybridization patt...

A molecular genetic linkage map based on tomato cDNA, genomic DNA, and EST markers was constructed for eggplant, Solanum melongena. The map consists of 12 linkage groups, spans 1480 cM, and contains 233 markers. Comparison of the eggplant and tomato maps revealed conservation of large tracts of colinear markers, a common feature of genome evolution in the Solanaceae and other plant families. Ov...

We have created a genetic map of Capsicum (pepper) from an interspecific F2 population consisting of 11 large (76.2-192.3 cM) and 2 small (19.1 and 12.5 cM) linkage groups that cover a total of 1245.7 cM. Many of the markers are tomato probes that were chosen to cover the tomato genome, allowing comparison of this pepper map to the genetic map of tomato. Hybridization of all tomato-derived prob...

BACKGROUND: The chromosomal polymorphism of short chromosomal polymorphism of short arms of acrocentric arms of acrocentric chromosomes and heterochromatin chromosomes and heterochromatin variations of variation of Chromosomes 1, 9, 16 and Y have been chromosomes 1, 9, 16 and Y also have been reported reported in humans. The pericentr ic inversion of Chromosome 9 is commonly seen in normal huma...
