	Model	λ Background x 10 3	λ Sternorrhyncha x 10 3	Fold increase	-ML	# Parameters	Likelihood ratio	p- value
APC	Single λ	1.2177	-	-	34.31	1	1.562	0.204
	Multiple λ	0.7307	2.5049	3.43	33.52	2
AAAP	Single λ	1.3119	-	-	38.33	1	6.633	0.008
	Multiple λ	0.3286	3.6802	11.20	35.01	2

λ represents the probability of gene duplication and loss per gene per million years.
