a Chromosomal location in the chicken (Gallus gallus).
b Sum of the branch lengths after rate smoothing in millions of years (MY). Divergence times were calibrated by assuming of a mid-Cretaceous (~100 MYA) origin of Neoaves. Differences among loci reflect the amounts of missing data.
c The number of inversion events based upon the MP criterion.
d The non-coding portions of two loci (EGR1 and MYC) include 820 bp of 3' UTR. All EGR1 non-coding sequence is 3' UTR and about half (330 bp) of MYC non-coding sequence is 3' UTR.
e CLTC and CLTCL1 were excluded for this estimate.
