Scientists are working on the possibility of cloning mammoths, but people are unsure about whether/if it will work.

Hi,
Do both whether and if work in the above? If not, could you tell me the reasons? Thanks.

Hi Angliholic

Just leave out about and the sentence is fine with either whether or if.

Thanks, Cool Breeze.

But what if "about" must stay, do both whether and if fit?

The sentence is wrong with about. Don't use it in the sentence. Drop it. About cannot be used in the sentence.
