Although we say “all fetuses essentially start as female,” it is correct to say “the blastocyst (the fetus before it is a fetus) is developed from the X chromosome, and most early development is driven by maternal mRNA.” RNA consists of bits of genetic code that are being expressed.
Do all mammals start as female?
