1 AP LAB #3part CCrossing Over during Meiosis in Sordaria… counting map units
2 Sordaria fimicola is a type of FUNGUS, found in the group known as ASCOMYCOTA “Sac fungi”
3 Ascus are found in here… in the ascocarp! The shared derived character that defines the Ascomycota is the ascus. It is within the ascus that nuclear fusion and meiosis take place.Ascus are found in here… in the ascocarp!
4 Sordaria fimicola~ ASCOMYCOTA See, here they are… ASCI!
5 Sordaria fimicola~ ASCOMYCOTA This is what it looks under a scanning e- microscope!
6 Sordaria fimicola~ ASCOMYCOTA Here they are… ASCI! ~ they hold ASCOSPORE
7 Sordaria fimicola~ ASCOMYCOTA Here they are… ASCI! ~ there are chromosomes inside those dots!!
8 In the ascus, meiosis occurs, followed by a round of mitosis In the ascus, meiosis occurs, followed by a round of mitosis. This leaves eight nuclei, and eventually eight ascosporesTHERE ARE CHROMOSOMES INSIDE THOSE SPORES… AND WITHIN THE CHROMATIN, THERE ARE GENES….These genes code for traits…COLOR
