In addition to humans and flies, some plants also make use of the XX/XY dosage compensation systems. Silene latifolia plants are also either male (XY) or female (XX), with the Y chromosome being smaller, with fewer genes expressed, than the X chromosome.
There has been evidence that the nonsense-mediated mRNA decay pathway participates in X chromosome dosage compensation in mammals. In higher eukaryotes with dimorphic sex chromosomes, such as humans and fruit flies, males have one X chromosome, whereas females have two.

The X chromosome, compared to an autosomal gene, contains more silent genes which influences measuring the amount of influence active genes have. RNA-seq data was preformed and the autosomal and X linked gene outputs were significantly different. This agrees with the fact that X dosage compensation is in respect to autosomes.
It's mostly business as usual, or close to it, on Wall Street as well as at the nation's banks, restaurants and fast-food chains today on New Year's Eve 2024.
The decision was announced by FIFA President Gianni Infantino following a virtual extraordinary Congress. The 2030 and 2034 World Cups each had only a single bid and both were confirmed by ...
In flies, acetylation of H4K16 on the male X chromosome by MOF in the context of the MSL complex is correlated with transcriptional upregulation as a mechanism for dosage compensation in these organisms. [2] In humans, the MSL complex carries out the majority of genome-wide H4K16 acetylation.
