C-Fern Sport Report
This mixture of wild type and a variety of mutant stocks (many uncharacterized) is an excellent way to introduce students to the wide variety of EMS-induced visible mutant types that can be observed in C-Fern gametophytes. Mutants such as albino, pale, polka dot, early gametophyte lethals and a variety of other types are present in a combined frequency of at least 10%. Some are very easily observed while others require more careful observations. Using isolation and selfing or crossing techniques, students can discover, confirm and characterize mutant phenotypes and determine dominance/recessiveness. |
