Counts and proportions of genes assigned to each normal distribution in a mixture model of $\underset{2}{log}\frac{M}{F}$ values

Distribution	Proportion	Mean	Variance
Element F genes (51 total)
1	0.41	− 1.020	0.041
2	0.36	− 0.225	0.069
3	0.23	0.038	0.001
Element A–E genes (5,602 total)
1	0.01	− 0.888	5.600
2	0.41	0.001	0.010
3	0.41	0.049	0.045
4	0.17	− 0.348	0.329

Genes have homologs in D. melanogaster on either element F or elements A–E
