Description
Andrew Rubio and co-authors ask, in a 2025 study, why frog and toad genomes vary so wildly in size, from tiny to enormous. Jumping DNA elements that copy themselves are prime suspects. The team compared sixty-one public frog genomes across twenty-two families and charted each element family's copy counts and ages.
Several element families tracked with bigger genomes, and recently active copies of one family mattered most. The activity was fairly recent in frog history, not ancient. Life history traits tied to size, like larval period and clutch size, also linked to the elements. The authors argue genome bloat in frogs is an ongoing process, still driven by fresh waves of jumping DNA.
