The evidence that a boy isn’t a girl is that a boy has XY chromosomes and a girl has XX chromosomes. The physical result of this chromosomal difference is a boy has male genitalia, higher testosterone levels, and typically greater physical strength than girls.it’s the same evidence that says a boy isn’t a girl. Funny how you idiots change the definitions and trust the science when convenient.
try having a backbone.
So what chromosomal or physical evidence can you offer that a human fetus is not a child?
Try having a sound argument.
