Figure 1From: Forelimb preferences in quadrupedal marsupials and their implications for laterality evolution in mammalsPercentage distribution of left-handed (L), right-handed (R) and ambipreferent (A) individuals in grey short-tailed opossums. The direction of manual lateralization in all types of behaviour studied (a,b,c,d) was found to be significantly influenced by the animals’ sex, therefore distribution is given separately for males, N = 12, and females, N = 14. Reversed distributions of limb preferences among subjects in two sexes could be traced: right-forelimb preference is more characteristic of males, while left-forelimb preferences are more typical for females.Back to article page
