Types of asci are compatible with gene conversion | Quick Homework Help

Suppose you are mapping the distance between the locus A and the centromere in Neurospora. You obtain nine types of asci presented below. Some of these asci indicate that ‘gene conversion’ phenomenon associated with the strand exchange without a mismatch repair may have taken place.

A. Which types of asci indicate this? (see digram below..)
