When more than one interacting gene pairs are involved the level of incompatibility as low as, or lower than, the level produced by the most incompatible interacting gene pair acting alone, that is: LIT1,2 less than L1T1 where:LIT1 less than L1T2.
The coefficient of .24 on the cumulative score (Lit1 + Lit2 + Lit3) implies that Nuestro Barrio viewers, on average, scored one-quarter of a point higher on the cumulative knowledge score than nonviewers.
