Verified step by step guidance

Understand that Sordaria is a fungus used to study genetic recombination through the analysis of asci, which contain spores arranged in a linear order reflecting meiotic events.

Recall that the different spore patterns (like 8:0, 4:4, 6:2, 2:2:2:2) represent different segregation types of alleles after meiosis and possible crossing over between linked genes.

Identify that a non-recombinant (parental) pattern typically shows all spores of one type together, such as 8:0 or 4:4, indicating no crossing over between the genes.

Recognize that recombinant patterns arise from crossing over and result in mixed arrangements of spores, such as 2:2:2:2, which indicates that the alleles have been shuffled due to recombination.

Conclude that the 2:2:2:2 pattern is a classic recombinant pattern in Sordaria asci, reflecting the presence of crossing over between linked genes during meiosis.
