The Sordaria Cross

Mr. Andersen explains the Sordaria cross, a biological experiment involving the fungi Sordaria fimicola. The video covers the process of meiosis, the life cycle of Sordaria, and the significance of crossing over. It also includes a lab procedure for analyzing genetic recombination and calculating gene distance. The importance of crossing over in genetic variation is highlighted, referencing historical figures like Thomas Hunt Morgan and Alfred Sturtevant.

What is Sordaria fimicola and where can it be found?

Describe the process of meiosis as it occurs in Sordaria.

How does the life cycle of Sordaria differ from that of humans?

What does a 4 to 4 spore ratio indicate in Sordaria experiments?

What is the significance of crossing over in the context of Sordaria?

Explain the importance of Thomas Hunt Morgan and Alfred Sturtevant in genetics.

How do you calculate the percent of crossover in Sordaria?
