  1. CAT activity of strains carrying two hemizygous copies of the LTR-CAT construct (see Additional file 1, Cross 1 for details of strain construction) are approximately equal to the values expected under the additive model (i.e., the sum of the CAT activities measured in two strains carrying single copies of the respective LTR-CAT constructs).
