19. EXERCISE 3B.2: Crossing over during Meiosis in Sordaria Number of 4:4 Number of Asci Showing Crossover Total Asci% Asci Showing Crossover Divided by 2 Gene to Centromere Distance (map units) LAB THREE Mitosis and Meiosis

20. EXERCISE 3B.2: Crossing over during Meiosis in Sordaria Why do we divide the % by 2? LAB THREE Mitosis and Meiosis

21. EXERCISE 3B.2: Crossing over during Meiosis in Sordaria Crossing over happened between these two chromatids… LAB THREE Mitosis and Meiosis

22. EXERCISE 3B.2: Crossing over during Meiosis in Sordaria Crossing over happened between these two chromatids… …but not between these two LAB THREE Mitosis and Meiosis

23. EXERCISE 3B.2: Crossing over during Meiosis in Sordaria Crossing over happened between these two chromatids… …but not between these two so it only happened ½ the time. LAB THREE Mitosis and Meiosis

24. EXERCISE 3B.2: Crossing over during Meiosis in Sordaria A map unit is equal to the % of time that crossover happens between two genes or between a gene and the centromere. LAB THREE Mitosis and Meiosis

25. EXERCISE 3B.2: Crossing over during Meiosis in Sordaria Map units show us relative distances between genes LAB THREE Mitosis and Meiosis

26. EXERCISE 3B.2: Crossing over during Meiosis in Sordaria Map units show us relative distances between genes. They do not translate directly into numbers of nucleotide pairs LAB THREE Mitosis and Meiosis

27. EXERCISE 3B.2: Crossing over during Meiosis in Sordaria Map units show us relative distances between genes. They do not translate directly into numbers of nucleotide pairs. Genes that are more than 50 map units apart assort independently… LAB THREE Mitosis and Meiosis

28. EXERCISE 3B.2: Crossing over during Meiosis in Sordaria Map units show us relative distances between genes. They do not translate directly into numbers of nucleotide pairs. Genes that are more than 50 map units apart assort independently… and might as well be on separate chromosomes. LAB THREE Mitosis and Meiosis
