Chiwawas are a breed....Anyway, analyzing any of the more prominent DNA sectors will show their legitimate gender.
Breeding is nothing but utilizing mutations, which almost every if not every disorder is.
Okay, again, please realize that gender <> sex. This is a definition thing.
Gender: the state of being male or female (typically used with reference to social and cultural differences rather than biological ones).
Sex: either of the two main categories (male and female) into which humans and many other living things are divided on the basis of their reproductive functions.
So while yes, you're technically right about their "true" sex, keep in mind that there are hermaphrodite species, such as various slugs, do exist. Because they have their own sex of hermaphrodite, the same can be applied to classify humans. Sex, gender, pretty much everything related to this subject is nothing but how humans are classified in regards to one another. The only underlying difference is dna, and if you want to claim that males and females are different things because their dna types are different, then having both would be different than both, not part of either or both. Like, purple. Purple has both blue and red, but it is it's own color. Even lighter shades are blue AND red, even if the red is in less amounts than other shades. It's still purple, which is still red and blue, but it's classified as it's own color instead of a shade of either red or blue.
Is that a better explanation?
