The thing that distinguishes one species from another on the genetic level is the genus because it is the level above species of the linnean system of clasification
The gene that expresses itself over the other is Dominant. The former gene is recessive.
Horizontal Gene Transfer is probably the term you are looking for
incomplete dominance
The process of combining genes from different organisms is known as genetic engineering. This involves isolating the desired gene from one organism, modifying it if necessary, and then inserting it into the genome of another organism. This can be achieved through techniques such as gene cloning, PCR, and gene editing tools like CRISPR.
This phenomenon is called epistasis. It occurs when the effect of one gene masks the effect of another gene at a different locus. Epistasis can result in complex patterns of inheritance.
Morphology of individual organism identifies and distinguishes one living thing from another.

Trait is a characteristic that distinguishes one person from another and that causes a person to behave more or less consistently.
The number of protons in the nucleus of an atom distinguishes it from another atom. This number is known as the atomic number and determines the element to which the atom belongs.
The topography is one characteristic that best distinguishes one landscape from another.

No. Evaporation is a physical process and it does not distinguish one substance from another.

An element's atomic number, or number of protons, differentiates one element from another.
