Earth-TRN454 is a gender flipped universe based on Earth-12041, where all characters, historical figures and landmarks are the opposite gender to each other.
Females also appear to be the more dominant sex, as shown when Spider-Girl and She-Goblin didn't take Spider-Man seriously for being a male. Combined with the fact that Petra took her mother's surname, that means it's likely that most children take after their mother's surname.
