ln[chill coma recovery time (CCRT)] results in relation to the X-chromosomal recombinant (XR) line genotype at marker position 24 cM for males and females. While females significantly decrease their CCRT when having the European genotype at this marker position (Welch’s t-test, P < 0.001), males tend to increase their CCRT. However, the difference in CCRT between the males with European and African genotype was not significant. Such contrasting patterns for males and females are called quantitative trait loci (QTL)–sex interactions.
