aThe number of genes that were assigned to each human chromosome (Build 35.1) [25].
bThe expected number of human salamander orthologies is based on random sampling from the human genome. This number is calculated as the proportion of genes that occur on a given human chromosome multiplied by the entire number of human/Ambystoma orthologies that were identified (N = 340). A single HSAY orthology is excluded from this table.
c"+" designates a positive deviation from the expected number,"-" designates a negative deviation from the expected number.
