Table 1 Comparative mapping of chicken chromosome paints A–G, and their ostrich and budgerigar orthologs
Chromosome paint ID | Chicken chromosome(s) | Ostrich orthologs (all microchromosomes) | Budgerigar orthologs |
|---|---|---|---|
A | 11 | 1 pair | Fusion as part of chromosome 5 |
B | 10 and 12 | 2 pairs | 2 pairs of microchromosomes (no apparent fissions/fusions at this resolution) |
C | 13 | 1 pair | 1 pair of microchromosomes (no apparent fissions/fusions at this resolution) |
D | 13 and 14 | 1 pair | 1 microchromosome pair +1 arm of chromosome 8 = fission and fusion at this resolution |
E | 10 and 12 | 2 pairs | 1 pair = fusion |
F | 16, 17 and 18 | 3 pairs | 2 pairs = fusion |
G | ~5 pairs smaller than 18 | No result | 3 pairs = 2 fusions (although some signals are weak so may be failure of hybridization) |
