Easy, rapid setup by teacher or students
Easy to grow
Rapid gametophyte development from spores over a 14-day period
Spore-to-spore life cycle in as little as 90 days
Simple genetics with striking mutant phenotypes (e.g., polka dot)
C-FERN® is easy to grow and its fast development and simple genetics make it a great teaching tool. First of all, C-FERN® requires little space-an area 22 x 10-1/2" is all you need for a class.
C-FERN® also has a rapid life cycle. Spores germinate within 3 to 4 days, giving rise to haploid gametophytes. At maturity (6 to 8 days) gametophytes produce eggs and sperm. Water triggers sperm release, so students can easily observe the process. The rapid growth of diploid sporophytes follows fertilization.
Because the gametophyte is an independent stage, C-FERN® is excellent for studies of plant life cycles and clearly shows the alternation of sporophytic and gametophytic generations. Since meiosis produces spores that germinate, giving rise to haploid gametophytes, the segregation of alleles in a genetic cross of wild type with polka dot can be visualized in the gametophytes.
The C-FERN® Manual: Teaching and Research (item#-156775) contains detailed culture instructions and a set of laboratory investigations. The manual and C-FERN® laboratory investigations were developed jointly by Drs. Leslie G. Hickok and Thomas R. Warne of the University of Tennessee with support from the National Science Foundation and the University of Tennessee.

Students visualize basic principles of Mendelian inheritance in C-FERN® by following the segregation of a visible marker, polka dot, in both the F

gametophyte and F

sporophyte generations. Students sow spores of an F

hybrid (wild type x polka dot) to produce F

gametophytes. By adding water to mature F

gametophytes, students visualize random fertilization events that produce the F

sporophyte generation. The large sample numbers provided from class and individual data sets allow meaningful use of the chi-square test.
Includes materials for 30 students. Experiment time is 14 to 28 days. Reusable with
