Most data on W chromosomes come from birds. The avian ZW chromosome system is around 140 million years old, and the Z and W are highly heteromorphic. The W has lost most of its genes in most species, with the exception of some palaeognaths (e.g. ostrich) which have a large PAR [18...

Although nucleosomes may look like extended "beads on a string" under an electron microscope, they appear differently in living cells. In such cells, nucleosomes stack up against one another in organized arrays with multiple levels of packing. The first level of packing is thought to produce a...
This finding suggests that neo-Y alleles can be distorted from normal expression level, either downregulated or upregulated, as a result of degenerating control of gene expression. Together with the mutation analysis results presented above, the expression patterns of the nine investigated genes ...

- 《Genome Biology & Evolution》 被引量: 0发表: 2017年 SEX-LINKED INHERITANCE OF VIRULENCE AGAINST WHEAT RESISTANCE GENE H9 IN THE HESSIAN FLY (DIPTERA, CECIDOMYIIDAE) The results suggest that vH9 and eye color loci are located on 1 of the 2 sex chromosomes of the Hessian fly, and the ...
Finally, chromosomes in the metaphase of meiosis contain a larger amount of material. Although extensive research has been devoted to chromosomes, the study of their structural and functional organization remains one of the most urgent tasks of modern biology. Chromosomes perform highly complex ...
