Introduction- Sordaria Fimacola is an ascomycete fungus that produces eight ascospores in each ascus, which are contained in perithecia. Because of the thin, long shape of the ascus, the positioning of the ascospores reflects the arrangement of homologous chromosome pairs during metaphase I of meiosis. Using this knowledge, we were able determine map locations for the tan spore and gray spore genes with respect to the centromere and to conclude whether genes are linked or unlinked. Methods- Three crosses were done in this study. During the first week, we obtained data on the gray spore black spore cross (gt + x g + t + ) and the tan spore black spore cross (g + t x g + t + ). For the tan spore, mutant strain and black spore, wild type strain cross, we obtained a petri dish containing the fungi with mature perithecia. We squashed the perithecia on a microscope slide in order to see the asci. We were concerned only with the perithecia that contain interstrain asci,

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
