Problem:

Assume that the + (plus/positive) mating type individual (red) produces wild-type spores and the - (minus/negative) mating type individual (blue) produces tan spores. Referring to your diagrams of the ascus types drawn in lab, create a diagram illustrating the stages of meiosis (including recombination between the wild-type and tan allele) followed by mitosis at the locations they occur in the sexual life cycle to produce the three different ascus types (you do not need to diagram any aspect of asexual reproduction).

Required:

Question 1: Be sure to link your drawings of meiosis for the different ascus types to the life cycle drawing

Question 2: How does the process of meiosis contribute to the genetic variation of Sordaria? (please provide the answer in a bullet list)

Question 3: How might increasing the frequency of recombination affect genetic variation? (please provide the answer in a bullet list)

Provide a brief explanation for your answer.
