| Research Abstract |
Some species of ferns ceased their sexual reproduction in their evolutionary process and produce their next generation through apogamy without fertilization. In that case, all their offspring are expected to be genetically identical. However, apogamous fern species frequently show large genetic variation. In this study, we clarified that apogamous fern species can obtain genetic variation from its related sexual species through hybridization. We could also show that apogamous fern can produce genetically variable offspring through genetic segregation.
