Predicted minimum gene number per species for mammals whose genome sequences are currently available. Genes are indicated below their α or β subunit heading. Pseudogenes are shown in parentheses. The phylogeny is modified from . Species names and data sources are provided in the Materials and Methods. Results for macaque and platypus are not shown owing to the absence of evidence for Abp genes in their current genome assemblies.
