given the following sentence

I have a snake of which the head is white and (of which) the tail is black.

In this expression, can I omit the second (of which)? Or shouldn't I omit it?

    I think omitting the second "of which" would improve the sentence. Other formulations seem even better. Consider the version using "with" in the answer from BladorthinTheGrey, and consider "I have a snake whose head is white and whose tail is black." Commented Dec 12, 2016 at 6:08

To answer your question: yes, you could omit the second of which and get away with it.

However, this sentence is not very good to start off with; usually, when describing attributes of an object, you use adjectives or the preposition with.

For instance:

I have a sneak with a white head and a black tail.


I have a white-headed and black-tailed sneak.

The first alternative—using with—is more idiomatic.

    Alternatively, one might use "I have a snake whose head is white and (whose) tail is black" or a combination like "I have a white-headed snake whose tail is black."

Yes, given that the conjunction "and" can be taken to subject the next phrase to the first "of which." And if the parentheses are original, they themselves are a clue because all that go between parentheses can always be dropped without harming the structure of a sentence (even though harming its meaning, as just in this parenthesized phrase!;).
