Turkey chromosome p-arm inversions identified in MGA5, MGA7, MGA10 and MGA13. Relevant chromosome segments are shaded. Large segments are banded to indicate directionality, also shown by colored arrows flanking enlargements. Centromeres are shown by constrictions. A. MGA5. MGA5p is inverted with respect to GGA5p with an additional small inversion of fragment 2 (yellow). Centromere location in MGA5p is tentative (see Results and discussion). B. MGA7. GGA7p is inverted with respect to MGA7 (fragment 1, direction indicated by blue arrow) with movement of the centromere to a telomeric site in MGA7. C. MGA10. GGA8p is inverted with respect to MGA10 with movement of the centromere to a telomeric site in MGA10. In addition, fragment 3 (yellow) is also inverted (such that its direction is now the same in both species), and we place a turkey genome segment (fragment 1, red) orthologous to a 340 kb fragment from GGA8_random at a telomere-adjacent location on MGA10. D. MGA13. GGA11p is inverted with respect to MGA13 with movement of the centromere to at or near the telomere in MGA13.
