What does dominantly mean?
Dominantly is an adverb meaning in a manner that is most important, prevalent, or controlling within a given context. It derives from the adjective dominant, which traces back through French to the Latin dominari, 'to rule or govern', itself formed on dominus, 'lord or master'. In practice, dominantly describes how a single element prevails over others: a region may be dominantly agricultural, a personality dominantly cheerful, a rock formation dominantly granite. It carries a formal, often scientific register and appears frequently in geology, genetics, sociology, and other descriptive fields. Writers should note that it overlaps heavily with predominantly — the far more common choice for expressing 'mostly' — and that dominantly is most apt when the nuance of command or ascendancy matters. Used precisely, it lends prose an air of authority and analytical clarity.
In a manner that predominates or constitutes the principal element.
"The diet of the species is dominantly insectivorous during the summer months."
In a manner that exercises control or commanding influence over others.
"The team adopted a dominantly defensive strategy in the second half."
It shares its root with 'dominion' — both trace back to Latin dominus, 'lord or master', so to do something dominantly is literally to act like the master of it.

Etymology of dominantly
Dominantly comes from the adjective dominant plus the adverbial suffix -ly. Dominant entered English in the early 16th century from French dominant, derived from Latin dominans, the present participle of dominari, 'to rule, govern, or master'. The Latin verb stems from dominus, meaning 'lord' or 'master', the same root that gives us dominion, dominate, and domineer. The adverb dominantly developed naturally alongside the adjective and has been used since at least the early modern period.
