One reads, "...this mechanism shares some similarities with sex-determination systems found in humans and other animals." Sex determination in humans? Nope. None identified and none detailed. This is an assertion slipped into the prose, expecting few to notice.
Additionally one reads later, "...this is similar to the way animal sex chromosomes work, with two structural variants (X and Y chromosomes in humans and other mammals) kept roughly in balance." Nope. "Similar" is neither explicated nor proven. The article's report of some academic work is become "political" for the sake -- most likely -- of supporting transsexual ideology. Which looks like this:
None of the transsexuals are getting their DNA altered in any way. Period.
