Ivyleaf morning glory (Ipomoea hederacea) has become a useful system for studying the genetics and ecology of leaf shape variation as this species exhibits two leaf shapes: leaves with entire margins, and 3-lobed leaves. It is known that these phenotypes are controlled by a single locus, and differ in their ecophysiology, geographic distribution, ecology, and fitness. However, individuals producing leaves with 1-2 extra lobes have also been observed, but the genetic basis of these phenotypes have not been described. To investigate the genetic basis of extra-lobing, we compared phenotypic distributions of leaf shapes of an F2 gen","pubDate":"2026-11-02","url":"https://www.biorxiv.org/content/10.64898/2026.10.27.762295v1?rss=1"},"indexado":"2026-11-03T03:04:05.727Z"}}
