Characterization of PAPs in 33 A. digitifera and six A. tenuis individuals. (a) The frequencies of single-copy genes under functional constraint (47%: 10,455) and multiple-copy genes or single-copy genes without functional constraint (53%: 11,917) for all CDSs (22,372). (b) The frequencies of PAPs (5%: 516) and non-PAPs (95%: 9939) for single-copy genes under functional constraint. (c) The frequencies of PAPs on single scaffolds. (d) The frequencies of each presence–absence status for 516 genes (PAPs in A. digitifera) in A. tenuis
