Table 3. Detection probabilities of the transgene for each of the five scenarios.

Scenario	1	2	3	4	5
Expected	0.83	0.83	0.74	0.76	0.77
Observed	0.01	0.03	0.14	0.19	0.46

The observed probabilities refer to the average frequency of trials in which the positive transgene was detected among ten repetitions. Expected probabilities are simple binomial probabilities based on the assumption of spatially homogenous transgene frequencies (see methods).
