What are the types of genarians?

There is no universally recognized term or classification system for "genarians." It's possible you're referring to a different term or have misunderstood something.

Could you please provide more context or clarify what you mean by "genarians"?

For example, are you referring to:

* Generations: Like Baby Boomers, Gen X, Millennials, etc.?

* A specific type of gene: Do you mean gene variants or alleles?

* A fictional group or concept: Perhaps from a book or movie?

Once you provide more information, I can help you better!
