The map of chromosome 20. [PDF]
Journal of Medical Genetics, 1988 The number of gene assignments to human chromosome 20 has increased slowly until recently. Only seven genes and one fragile site were confirmed assignments to chromosome 20 at the Ninth Human Gene Mapping Workshop in September 1987 (HGM9). One fragile site, 13 additional genes, and 10 DNA sequences that identify restriction fragment length ...

Using Orientation to Distinguish Overlapping Chromosomes [PDF]
arXiv, 2022 A difficult step in the process of karyotyping is segmenting chromosomes that touch or overlap. In an attempt to automate the process, previous studies turned to Deep Learning methods, with some formulating the task as a semantic segmentation problem. These models treat separate chromosome instances as semantic classes, which we show to be problematic,

Identification of genetic linkage group 1-linked sequences in Japanese eel (Anguilla japonica) by single chromosome sorting and sequencing. [PDF]
PLoS ONE, 2018 Japanese eel (Anguilla japonica) constitutes one of the most important food fish in Japan; accordingly, genome sequencing and linkage mapping have been conducted for the purpose of artificial cultivation.

Parasite, 2023 The cytogenetics of Acanthocephala is a neglected area in the study of this group of endoparasites. Chromosome number and/or karyotypes are known for only 12 of the 1,270 described species, and molecular cytogenetic data are limited to rDNA mapping in ...

Two-Parameter Characterization of Chromosome-Scale Recombination Rate [PDF]
Genome Research, 19:2300-2307 (2009), 2009 The genome-wide recombination rate ($RR$) of a species is often described by one parameter, the ratio between total genetic map length ($G$) and physical map length ($P$), measured in centiMorgans per Megabase (cM/Mb). The value of this parameter varies greatly between species, but the cause for these differences is not entirely clear.

The Trypanosoma cruzi Genome Project: Nuclear Karyotype and Gene Mapping of Clone CL Brener
Memorias do Instituto Oswaldo Cruz, 1997 By using improved pulsed field gel electrophoresis conditions, the molecular karyotype of the reference clone CL Brener selected for Trypanosoma cruzi genome project was established.

A Novel Application of Image-to-Image Translation: Chromosome Straightening Framework by Learning from a Single Image [PDF]
arXiv, 2021 In medical imaging, chromosome straightening plays a significant role in the pathological study of chromosomes and in the development of cytogenetic maps. Whereas different approaches exist for the straightening task, typically geometric algorithms are used whose outputs are characterized by jagged edges or fragments with discontinued banding patterns.

Polytene chromosome map and inversion polymorphism in Drosophila mediopunctata
Memorias do Instituto Oswaldo Cruz, 2002 Drosophila mediopunctata belongs to the tripunctata group, and is one of the commonest Drosophila species collected in some places in Brazil, especially in the winter. A standard map of the polytene chromosomes is presented.

Construction of whole genome radiation hybrid panels and map of chromosome 5A of wheat using asymmetric somatic hybridization. [PDF]
PLoS ONE, 2012 To explore the feasibility of constructing a whole genome radiation hybrid (WGRH) map in plant species with large genomes, asymmetric somatic hybridization between wheat (Triticum aestivum L.) and Bupleurum scorzonerifolium Willd. was performed.

Bifractal nature of chromosome contact maps [PDF]
Phys. Rev. Research 2, 043078 (2020), 2019 Modern biological techniques such as Hi-C permit to measure probabilities that different chromosomal regions are close in space. These probabilities can be visualised as matrices called contact maps. In this paper, we introduce a multifractal analysis of chromosomal contact maps. Our analysis reveals that Hi-C maps are bifractal, i.e.
