Comparison of positive ratios and average overall and positive yield ratings from four clone subsets that were tested in all pairwise combinations.

	Cosmopolitan		Belfast Lough
	Unbiased	Biased	Unbiased	Biased
Positive ratio	0.250	0.429	0.159	0.181
Average yield rating	0.694	0.616	0.394	0.305
Average positive yield rating	2.78	1.44	2.17	1.68

Positive ratio is the proportion of co-cultures that were found to produce hypnozygotes. Average yield rating is the mean of yield ratings (0, 1, 2 or 3) from all subset co-cultures. Average positive yield rating is the mean of all subset cocultures rated 1, 2 or 3. See text for further description of biased and unbiased subsets.
