A cross between two yeast strains with the following genotypes a+ b+ c+ x a b c (three linked genes in this order) gave yeast rise to a tetrad ascus containing the following spores: a+ b+ c+, a+ b c, & a b c. The joint molecule that formed between two non sister chromatids in this region of the chromosome is shown in the diagram below. The numbered boxes in the diagram indicate specific features or events that may or may not have occurred during the formation of the spores. When answering the question, refer to the box numbers to indicate a specific location or feature of the DNA molecules.
a) Indicate the appropriate labels that would replace each of the boxes labeled 1-4?
b) What term describes the region indicated by box 5?
c) Describe the events that occurred in prophase 1 to generate the spores indicated above using the numbered boxes to refer to specific parts of the drawing (some of the numbered boxes you will not need to include, if there are two alternates, you only need to give one of them)
d) At what stage of Prophase 1 would the molecule shown in the diagram be present?
