Mean ln[chill coma recovery time (CCRT)] in males (a) and females (b) of the X-chromosomal recombinant (XR) lines of Drosophila melanogaster. The smooth increase indicates multiple quantitative trait loci (QTL) with small to intermediate effects. Paternal cold tolerance (E*, grey triangle on the x-axis) as well as cold sensitivity (A*, black triangle) was not significantly higher in the males of the XR lines, whereas the females of one XR line showed a significantly shorter CCRT than the E* line (Welch’s t-test and Holm–Bonferroni correction, P < 0.05).
