C-Fern Educational Kits Genetics in Action - Mendelian Genetics Kit (15-6750)
Students visualize basic principles of Mendelian Inheritance in C-Fern by following the segregation of a visible marker, polka dot, in both the F1 gametophyte and F2 sporophyte generations. Students sow spores of an F1 hybrid (wild type X polka dot) to produce F1 gametophytes. By adding water to mature F1 gametophytes, students visualize random fertilization events that produce the F2 sporophyte generation. Hypotheses generated from observations of F1 gametophytes are then tested by analysis of phenotypes and ratios in the F2 sporophyte generation. The large sample numbers provided from class and individual data sets allow meaningful use of the Chi-square test. This investigation demonstrates the Mendelian principles of segregation, random fertilization and dominance/recessiveness and provides hands-on experience in data acquisition, hypothesis formation and testing. Materials for 30 individuals. Experiment time is 14 -28 days.
