Analysis of C. remanei fem-3 and tra-2 genes

Gene	Pathway	dN/dS	M7-vs-M8	Proportion of sites with dN/dS>1
fem-3	B	0.23	10.42	2.3
tra-2	B	0.37	1.23	0.7

The fem-3 and tra-2 intraspecies data from Haag and Ackerman (2005) were analyzed using both pairwise and site-based methods. Using M7 -vs- M8 models LRT rejects the null for fem-3 (Df = 2, χ²_l = 9.2103, P < 0.01, bold) but not for tra-2. B = involved in somatic and germ line sex determination. dN/dS = average pairwise. Proportion of sites with dN/dS>1 = ratio of selected sites with a probability higher than 0.5 of dN/dS>1 to total sites.
