Cumulative distribution of the fraction of total recipients whose fraction of donor thymocytes is equal to or less than that listed on y-axes.
(A) Lewis recipients receiving NBr marrow. (B) C3H/HeN recipients receiving AKR/J marrow. For both species, the cutoff value was set at 4% or greater for positive animals, whereas less than 4% was used to score animals as being negative.
