In experiment 6 the cage number is specified.
At the field site location, small cages were placed in the field laboratory.
Number of mixed batches with the hypothesis of 1∶1 ratio of OX3604C∶GDLS2 larvae not rejected by Chi Square Test. For statistical analysis, this number was included in the number of OX3604C matings because we assumed they came from matings with heterozygous males and not from occasional double matings.
= statistically significant results.
