Dapper - pass whole entity as query parameter or anonymous object

Question

I want to know if there are any recommendations with query parameters

Is it ok to pass the whole object or is it better to create a lightweight anonymous object with properties I need?

Query<SomeObj>("Select * from SomeObjs where Id = @Id", someObj);

or

Query<SomeObj>("Select * from SomeObjs where Id = @Id", new {someObj.Id});

Are there any performance or memory implications for one over other?

For how Dapper works, by creating and caching the mapping code on the fly at the first use, it doesn't really matter.
