Pairwise Duplicate Retention Data from the Oikopleura dioica Genome (Denoeud et al. 2010) Right Truncated at dS = 0.3 Was Fit with the General Death Model

Components	Model	AIC	N0	b	c	d	f	q
1	Neo	Yes	65.6	115	0.948	5.03	130
2	Neo	No	64.8	39.3	0.112	115	23.8	0.42
	Neo			46.2	0.725	4.45	74.0

NOTE.—AIC was used to compare parameterizations within a component class and between mixtures with different numbers of components. Using a fit to binned data, the best supported model was a one-component neofunctionalization model.
