NA, not applicable.
α
Chromosome structures found at heterozygous state in parent indicated by (°).
β
bp means breakpoint; T1 and T8 refer to translocated fragments of 1/4 or 2/8, respectively.
γ
Calculated excluding aneuploid on translocated chromosome individuals (i.e. calculated on green cells of Table S2).
δ
1' refers to individuals for which segmental aneuploidy at the end of chromosome 1 is observed but could not be explained.
ζ
Statistics calculated for the 1/9 translocation.
ε
Statistics calculated for the 2/8 translocation.
*
Population described in Hippolyte et al. (2010).
**
Population described in Martin et al. (2017).
T
Refers to tetraploid parent.
