Male Y chromosomes not ‘genetic wastelands’

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. The research provides new insights into the processes that shape the Y chromosome, adding to the evidence that, far from a genetic wasteland, Y chromosomes are highly dynamic and have mechanisms to acquire and maintain genes.
