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. En este estudio se analiza la variación alozimática y genotípica de leucin-aminopeptidasa (Lap-2) y fosfoglucomutasa (Pgm) en Procambarus clarkii de Baja California, México, sometido a diferentes condiciones térmicas. La exposición sucesiva de los organismos a la temperatura crítica máxima (TCMax) no evidenció una respuesta de endurecimiento. Sin embargo, existen diferencias en las frecuencias alélicas y genotípicas de Lap-2 y Pgm entre los organismos aclimatados a 20 y 33°C y la población proveniente del campo. Por otro lado, las frecuencias de los genotipos heterocigotos de Lap-2 y Pgm son más altas en las TCMax final de 20 y 33°C en comparación con la población proveniente del campo. Estos resultados demuestran una variación en las frecuencias alozimáticas y genotípicas que son determinadas por el efecto de la temperatura en P. clarkii. Se observa, además, una selección a favor de los organismos heterocigotos en las TCMax.
