[Transformers] What causes some Transformers to have genders?

As commonly seen, most TF's are the male body type but there's a small number of TF's that are female body type.

What causes this?

I've been recently thinking about this and thought the spark of a TF is similar to our souls. What the spark chooses to be, determines their body type. Is this true?

(In regards to originals.) Humans, actually. Normally Transformers don't have gender features, as they are an asexual species. While by default, they naturally take a masculine form, it's their interactions with humans that make some like Arcee take a feminine form. Mostly for aesthetic reasons.
