TL;DR: Methylated lysine 9 of histone H3 (Me9H3) is a marker of heterochromatin in divergent animal species and is enriched in the inactive mammalian X chromosome in female cells, as well as in the XY body during meiosis in the male, and forms a G-band pattern along the arms of the autosomes.
Journal ArticleDOI
Heterochromatin and tri-methylated lysine 20 of histone H4 in animals.

TL;DR: Evidence that Me( 3)K20H4 is dependent upon H3-specific Suv(3)9 histone methyltransferase activity, suggesting that there may be `epigenetic cross-talk' between histones H3 and H4 is presented, and it is shown that in coccids it is present on the facultatively heterochromatinised paternal chromosome set.
Journal ArticleDOI
The Relationship Between DNA Methylation and Chromosome Imprinting in the Coccid Planococcus citri
TL;DR: The data suggest that the two haploid sets are imprinted by parent-of-origin-specific DNA methylation with no correlation with the known gene-silencing properties of this base modification.
Journal ArticleDOI
Inverted meiosis and meiotic drive in mealybugs
TL;DR: It is revealed that at the second meiotic division in males a monopolar spindle is formed, to which only euchromatic chromosomes become attached, and this might represent an adaptation to chromosome holocentrism.
Journal ArticleDOI
Identification of a short region on chromosome 6 affecting direct calving ease in Piedmontese cattle breed.
TL;DR: Linkage Disequilibrium (LD) analysis showed high correlation between SNPs located within LAP3 and LCORL indicating a possible selection signature due either to increased fitness or breeders’ selection for the trait.
