In flies the process is inverted: male cells up-regulate the transcription of the single chromosome X by two-fold to generate the same gene output as females. The dosage compensation process in ...

Researchers have found a way to sequence a large portion of the Y chromosome in the fruit fly Drosophila melanogaster -- the most that the Y chromosome has been assembled in fruit flies.

These genes were mapped on the chromosome, and were used to create a gene knock ... For the first time sexual dimorphism was found in the brains of several species of Hawaiian Drosophila., in which ...

"Our identification of a protein that acts both to establish and protect cohesion in Drosophila chromosomes may represent an intermediate stage of the evolutionary inheritance of factors involved ...

Like mammals, the fruit fly Drosophila has two different sex chromosomes, with XX females and XY males. A study published on July 12th in PLOS Biology shows that in the Drosophila testes--where ...

Recently developed genomic technologies have shed light on the genomic composition of the ancient Y chromosomes of some primates and Drosophila melanogaster and have shown that Y chromosomes in ...

Researchers have uncovered a "selfish" X chromosome in the fruit fly Drosophila testacea that manages to distort inheritance in both sperm and eggs. "But until now, we've only ever seen a ...

reveals how this small chromosome that arose less than 20 years ago has persisted in a single, lab-reared strain of the fruit fly, Drosophila melanogaster, and is correlated with supernumerary ...

D. melanogaster has only four pairs of chromosomes, compared to the 23 pairs in humans. This simplicity was one of the reasons why they were first used in genetic studies; Drosophila genes could ...

Some genes just don’t play fair. Researchers have uncovered a ‘selfish’ X chromosome in the fruit fly Drosophila testacea that manages to distort inheritance in both sperm and eggs. “Researchers have ...
