Here is an example:
- My father did not visit the exhibition and neither did I.
Is it OK to say the same in the following way:
- My father did not visit the exhibition and so did I.
Is there any difference in the meaning?

The phrase and so does when it joins two clauses means "and the same positive assertion is true of" (emphasis on positive assertion).
John has brown eyes and so does Jane.
John has brown eyes and the same assertion is true of Jane. She too has brown eyes.
The phrase and neither does when it joins two clauses means "and the same negative assertion is true of" (emphasis on negative assertion).
John does not have blue eyes and neither does Jane.
John does not have blue eyes, and the same assertion is true of Jane. She too does not have blue eyes.
P.S. The predicate of the second clause is implicit (have brown eyes...not have blue eyes).
English grammar, aside, your second sentence doesn't make logical sense. If your father did one thing and you did the opposite, we would expect to see a "but" to indicate there is going to be a change in direction:
My father did not visit the exhibition but I did.
Otherwise you want to say that you did the same thing:
My father did not visit the exhibition, and I didn't either.
Your first example says this more concisely:
My father didn't [do X] and neither did I.
We don't use also like this. We could use it in the way you want to, but we don't.
My father did not visit the exhibition and I did not also. No matter how we try to word it, it is awkward in English. The word is used consistently to mean an positive assertion, not a negative assertion/negation.
