IMHO this is stupid because mewtwo and mew are both genderless in the first place
Mew in games gave birth and it is genderless.
The reason it did, is because the Legendaries (non-gender) Pokemon take on traits to suit a masculine (male) or feminine (female) personality. Regardless if they have no gender.
However, I don't think they'll give Mewtwo or this form a gender.
Every time I saw the the statement "mew gave birth" i always took this as a figurative term
It was literal in the games. Just like the gender thing I mentioned, the Pokemon take on genders based on traits they have or act towards.
So for instance, if Mewtwo in the anime wanted to it could appear more like a female if it decided to take on said traits. --- Only insecure and ignorant people try to debase someone online based on their username.

Mewtwo in and of itself is more masculine. (Trait wise) being non-gender doesn't mean anything in Pokemon which has been shown again and again. --- Only insecure and ignorant people try to debase someone online based on their username.
