  • Large-scale fissions and fusions are informed by Slate et al. (2002) and confirmed in this study through sequence alignment (Table S5). CEL, C. elaphus; Chr, chromosome; BTA, Bos taurus; OAR, Ovis aries.

  • a Sheep chromosomes OAR1, OAR2, and OAR3 are fusions of BTA1 and BTA3, BTA2 and BTA8, and BTA5 and BTA11, respectively. OAR9 has a translocation from its homolog of BTA9 to its homolog of BTA14.

  • b Indicates where fission chromosomes would have had to have formed a new centromere.
