The gen part of transgenic comes from genes, not gender.

Transgenic refers to an organism or cell whose genome has been altered by the introduction of one or more foreign DNA sequences from another species by artificial means.[1][2]

Trumps’s team grabbed the term to anger credulous people and get their support. Trump might not know what it means, but his team does, and they don’t care. I expect depatru knows what it means as well, or is capable of finding it out. But he’d rather add to the manipulation.

I’m linking to both genome.gov and to Wikipedia in case the government site is taken down.
