Comparative chromosome painting discloses homologous Segments in distantly related mammals [PDF]

open access: yes, 1994
Comparative chromosome painting, termed ZOO-FISH, using DNA libraries from flow sorted human chromosomes 1,16,17 and X, and mouse chromosome 11 discloses the presence of syntenic groups in distantly related mammalian Orders ranging from primates (Homo

Chromosome number evolution in skippers (Lepidoptera, Hesperiidae)

open access: yesComparative Cytogenetics, 2014
Lepidoptera (butterflies and moths), as many other groups of animals and plants, simultaneously represent preservation of ancestral karyotype in the majority of families with a high degree of chromosome number instability in numerous independently ...

Characterisation of species and diversity of Anopheles gambiae Keele Colony [PDF]

open access: yes, 2016
Anopheles gambiae sensu stricto was recently reclassified as two species, An. coluzzii and An. gambiae s.s., in wild-caught mosquitoes, on the basis of the molecular form, denoted M or S, of a marker on the X chromosome. The An.

The elusive evidence for chromothripsis. [PDF]

open access: yes, 2014
The chromothripsis hypothesis suggests an extraordinary one-step catastrophic genomic event allowing a chromosome to 'shatter into many pieces' and reassemble into a functioning chromosome.

Multicolour interphase cytogenetics: 24 chromosome probes, 6 colours, 4 layers [PDF]

open access: yes, 2011
From the late 1980s onwards, the use of DNA probes to visualise sequences on individual chromosomes (fluorescent in-situ hybridisation - FISH) revolutionised the study of cytogenetics.

Number of nucleoli in diploids and polyploids of the genus Achillea L.

open access: yesActa Societatis Botanicorum Poloniae, 2014
Nucleoli were counted in 9228 interphase nuclei of the apical root meristem of 40 Achillea L. taxa (di-, tetra-. hexa- and octoploids). It was established that the distribution of nucleoli number in an interphase nucleus can be used as a rough practical ...
