  • The number of genes that are syntenic, nonsyntenic, and transposed in the genome, among genes with a homoeolog, among single-copy genes, and among genes with CNSs. χ2 for transposed homoeologs is based on the number of genes that have transposed in the genome. χ2 for total CNSs is based on the number of transposed genes that had a homoeolog. n/a, not applicable.
