There's no division into "1st imprint" and "2nd imprint". It doesn't matter which order you put your imprints in for a new incubation, all that matters is what info those imprints have inside them.
If an imprint from parent #1 is a Chesa, and imprnt from parent #2 is a Sunika, then the offspring has 50% chances of being a Chesa and 50% of being a Sunika. But if, for example, both parents have lotus fur pattern, then their offspring has 100% to be a lotus. Same rules apply for energy colours, fur colours, and body types.
