總結: In this study, the allozymic and genotypic variation of leucine-aminopeptidase (Lap-2) and phosphoglucomutase (Pgm) in Procambarus clarkii from Baja California is analyzed, under different thermic conditions. The repeated exposure of the organisms to the critica1 thermal maximum (CTMax) did not show a hardening response. However, there are differences in the allelic and genotypic frequencies of Lap-2 and Pgm among the organisms acclimated at 20 and 33°C and the field population. On the other hand, the frequencies of the heterozygote genotypes of Lap-2 and Pgm are higher in the final CTMax of 20 and 33°C compared to the field population. These results show a variation in the allozymic and genotypic frequencies which are determined by the effect of temperature on P. clarkii. Also observed is a selection in favor of the heterozygote organisms in the CTMax.
