Relationship between the size of an inversion (as percentage of the total chromosome size) and its effect on embryo mortality (meta-analytic summary of dominance effects across three captive populations (“Seewiesen”, “Bielefeld”, and “Cracow”). Shown are the odds ratios ± 1 standard error. An odds ratio >1 indicates an increased rate of embryo mortality in offspring produced by females or males that are heterozygous for one of the four inversions on chromosomes Tgu5, Tgu11, Tgu13, and TguZ. The effects on chromosome Tgu13 and TguZ for males both translate into a 4.5 % increase in embryo mortality rate. Only males can be heterozygous for chromosome TguZ. For visibility, values on the abscissa were moved 1 % up and down for females and males, respectively
