article or no article

May I write: A gander is a male, or must it read, A gander is male. ?

Without more context, I'd be more likely to use 'the male', asssuming you're trying to distinguish the male from the female. Howver, you could use both of the forms you suggest, though the second is more likely. Could you give the context for this?

Grammar exercise - use a, an, the or no article:

___ geese are birds. ____ goose is _____ female, but ______ gander is ____male.

I think it could be the goose/gander or a goose/gander. I'm not sure if I should think of male/female as an adjective (and not use an article) or as a noun (and use an article).

It is a terrible exercise, because it should state that there are several possible answers.
There are so many combinations of correct answers: The/a goose is the/a/--- female, but the/a/ gander is the/a/--- male.
AND... Goose is female, gander is male would be acceptable in spoken English.
