Cluster	Number of proteins	Number of heterotic proteins	Proportion of heterotic proteins	Chi-square standardized residuals
1	11	7	0.64	4.42^a
2	168	35	0.21	2.56^a
3	39	3	0.08	−1.07
4	65	22	0.34	4.40^a
5	144	13	0.09	−1.69
6	102	13	0.13	−0.35
7	627	72	0.11	−2.39^b
8	24	5	0.21	0.91
9	50	2	0.04	–1.93^b

Clusters significantly enriched in heterotic proteins.

Clusters significantly depleted in heterotic proteins (P-value, 0.05).
