I created a genderless pet and now I want to make it a girl, if I use a gender berry on it, will it give me the option to choose its gender?

[-Winks] Alas, no, the genderless to gendered option will always result in a male, so you will have to use two gender berries to make the pet female.

Alternatively, if you're okay with risking a species/color change, you could use the zapper until it changes the gender of your pet.

Damnit. >;/ Gotta buy two then. F. Won't risk the zappys, Thanks for the answer! ;-;

[-Winks] if you have an open pet slot, you could always create a new female pet and then swap its name with the genderless pet. name changes & swaps are free now.
