I am currently writing the introduction to my thesis and I want to say that two genes are next to each other. I would like to use the word "proximity" without saying "close proximity" but am unsure whether it implies the closeness that I want the sentence to.
I have read the thread regarding "close proximity" as a tautology and fear that choosing to use it in my thesis will be considered unsophisticated or be marked as poor language usage.
I have considered using "beside" or "next to" as in "the genes are beside/next to each other" but feel that it is too unsophisticated.
In context, this is what I have:
"Both genes are located on chromosome 1 (for example) and their proximity suggests that both are ..."
I'm open to suggestions other than "proximity" as well.
