Since RNs occur at sites of crossing over and SCs with their associated chromatin represent pachytene chromosomes, this map will show the distribution of crossing over on pachytene chromosomes. In spite of the limited number of characteristics available for identification of SCs, we have observed a good overall correspondence between the SC karyotype and the pachytene karyotype that is based on squashed chromosomes.
Work is underway to verify SC identification using heterozygous inversions.
