The slit above the tail has 2 small lumps above it if it is a male. No lumps if a female. It is extremely hard to tell without experience. Take it to a local pet shop that deal in reptiles and they will be able to sex it for you. Males also usually have more smaller black spots when they are fully grown and are brighter than a female. Again hard to tell unless you have one of each.
turn them upside-down and if there is a line it is a girl and if there is two dots it is a boy. April bray.
Depends on the species, most male geckos have a noticeable bulge, or large pores. It's difficult to tell until they reach maturity.
leopard geckos will have a swelling where the tail starts on the stomach side and dots by the pelvic area shaped like a V if its a male. not sure about panther geckos though

by asking its mother if it is a girl or a boy and plus you can tell by the face
you can tell if its a girl or a boy byits butt or eyes. if its a girl, it will have small pupils. if itsa boy, it will have large pupils.
i don't know if it is a boy or a girl
It can be either way, a girl can tell a boy that she loves him or a boy can tell a girl that he loves her.
