Uncovering Proximity of Chromosome Territories using Classical Algebraic Statistics [PDF]
arXiv, 2014 Exchange type chromosome aberrations (ETCAs) are rearrangements of the genome that occur when chromosomes break and the resulting fragments rejoin with other fragments from other chromosomes. ETCAs are commonly observed in cancer cells and in cells exposed to radiation.

Chromosome number variation in two antipodean floras [PDF]
AoB Plants, 2011 Italy and New Zealand are very similar in shape, extension, altitudinal and latitudinal range but located in opposite hemispheres. This paper compares variation in chromosome number in these two hotspot regions.

A deep dive into the ancestral chromosome number and genome size of flowering plants.
New Phytologist, 2020 Chromosome number and genome variation in flowering plants has stimulated a blossoming number of speculations about the ancestral chromosome number of angiosperms, but estimates so far remain equivocal.

Journal of Systematics and Evolution, 2021 Changes in holocentric chromosome number due to fission and fusion have direct and immediate effects on genome structure and recombination rates. These, in turn, may influence ecology and evolutionary trajectories profoundly.

Optimization of chromosome preparation and chromosome number and ploidy in Hemiboea
Guangxi Zhiwu, 2023 Chromosome number and genome ploidy are crucial basic information for systematic evolutionary biology and genetics. Hemiboea, a genus of Gesneriaceae, with about 44 species, is mainly distributed in southern China, which have important medicinal and ...

Karyotype analysis of some Onobrychis (sainfoin) species in Turkey [PDF]
Archives of Biological Sciences, 2012 In this study, karyotype analysis of the species of Onobrychis sp. was undertaken using the squash method. The results showed that the chromosome number of Onobrychis tournefortii (Willd.) Desv., O. gracilis Besser, O. hypargyrea Boiss. is 2n = 14 and

The Chromosome Number of Man [PDF]
Hereditas, 1956 Desde su aparición en 1944 la Estación Experimental de Aula Dei (EEAD) contempló objetivos de investigación básicos y aplicados, adecuando sus líneas de trabajo a las necesidades de investigación de cada momento. Gracias a una acertada política de reclutamiento de talentos, desde muy temprano se consagró como uno de los centros nacionales de referencia

Chromosome numbers in Bromeliaceae [PDF]
Genetics and Molecular Biology, 2000 The present study reports chromosome numbers of 17 species of Bromeliaceae, belonging to the genera Encholirium, Bromelia, Orthophytum, Hohenbergia, Billbergia, Neoglaziovia, Aechmea, Cryptanthus and Ananas. Most species present 2n = 50, however, Bromelia laciniosa, Orthophytum burle-marxii and O.
