I would think that the biological gender traits would manifest itself but making such a claim in a "genderless" time is controversial.
Out of curiosity I found an article about a boy who was raised as a girl due to an accident during a circumcision in the 60s. This part was interesting:
"Yet by the time Brenda reached puberty at 13, she was feeling suicidal.
"I could see that Brenda wasn't happy as a girl," Janet recalled.
"She was very rebellious. She was very masculine, and I could not persuade her to do anything feminine. Brenda had almost no friends growing up. Everybody ridiculed her, called her cavewoman.
"She was a very lonely, lonely girl."
Faced with their daughter's sadness, Brenda's parents stopped taking her to see Dr Money.
Soon after, they did the one thing Dr Money had warned them against: they told her she had been born a boy.
Within weeks Brenda had chosen to become David."
The incredible story of the boy who was raised as a girl after a tragic accident burnt off his penis.
