Table 1. Number of paralogous gene pairs with a high divergence rate of protein sequence and/or expression in the high and low morphological diversification groups.

Morphological divergence	Protein	Divergent expression	Not divergent expression	p-value^c
High	Divergent	16	30 (59%)^b	0.21
	Not divergent	21 (41%)^a	76
Low	Divergent	13	32 (67%)^b	0.02
	Not divergent	16 (33%)^a	116
High or Low	Divergent	29	62 (63%)^b	0.01
	Not divergent	37 (37%)^a	193

a Proportion of paralogous gene pairs with a higher expression divergence but no protein divergence.

b Proportion of paralogous gene pairs with a higher protein divergence but no expression divergence.

c Null hypothesis is that the proportion of paralogous gene pairs with a higher expression divergence is the same proportion of paralogous gene pairs with a higher protein divergence.
