Figure 4

Variation of L. sinapis chromosome number across geographical longitude. Chromosome number is inversely correlated with longitude according to a linear function (r = 0.826; p < 0.0001). Results based on 23 specimens with unambiguous chromosome number counts (Spain - 4, France - 2, Italy - 2, Romania - 8, Kazakhstan - 7).
