Human + ≥ 2 orthologs	17,489	15,315	14,973	14,266	12,823	13,696
Incomplete transcripts	6,113	5,317	5,219	5,037	4,562	4,938
Recent duplications	2,273*	745	816	1,476	1,319	1,089
After duplication removal	16,529	14,570	14,157	12,790	11,504	12,607

*: Recently duplicated genes are removed, but orthologs sets are retained if they still contain a human gene and ≥2 orthologs.
