Catagorical analysis

#1
Hello,
I really need help deciding what statistical test to use, as I don't normally work with categorical data! I think I want to see if there is a significant difference between weak, intermediate and strong frequencies for between A and B at each temperature, and also if there is a change in frequency within each temperature.
F R E Q U E N C Y
Genotype Temperature Weak Intermediate Strong
A 18°C 40 8 0
B 18°C 32 9 0
A 25°C 7 22 11
B 25°C 0 11 30
A 27°C 14 27 4
B 27°C 0 12 28


Should i use a MANCOVA? Im really not sure, any help would be great!!
