What type of conditions might effect crossing over in Sordaria?

Answer 1

Conditions like temperature, exposure to mutagens, and specific alleles can affect crossing over in Sordaria.

Step-by-step explanation:

Conditions that can affect crossing over in Sordaria include temperature, exposure to mutagens, and the presence of specific alleles.

Temperature: Lower temperatures allow for more crossing over to occur, while higher temperatures can inhibit or reduce the frequency of crossing over.

Mutagens: Exposure to mutagens, such as certain chemicals or radiation, can increase the frequency of crossing over.

Alleles: The presence of specific alleles can affect the likelihood of crossing over, as some alleles may promote or inhibit the process.

Answer 2

To observe crossing over in Sordaria, one must make hybrids between wild-type and mutant strains of Sordaria. ... When mycelia of these two different strains come together and undergo meiosis and then mitosis, the asci that develop will contain four black ascospores and four tan ascospores.
