Species A : 2N = 24, N = 12
Species B : 2n = 26, n = 13
During the hybridization N + n = 25
I think B seems like the answer.

Nervous Tissue -- signal conduction
Epithelial Tissue -- protection of organ
Muscle Tissue -- contraction and relaxation
Connective Tissue - structural support
The answer you are looking is the carbon cycle.
