Gene Mapping in Ascospore Sordaria Cultures by Recombination Abstract The laboratory experiment demonstrates the process of meiosis using the Sordaria Fimicola fungi. Meiosis is important because it is the process that generates diversity in genetics. A wildtype was crossed with two mutant types: tan and grey. In order to exhibit recombination‚ the sequence of ascospores needed to result in a 2:2:2:2 or 2:4:2 sequence. From the crossover
