President Trump delivered a series of executive orders after being sworn into office, one of which declared that the US government will recognise "only two genders, male and female" on government-issued identification. More specifically, the order defines someone female as "a person belonging, at conception to the sex that produces the large reproductive cell," whilst someone male is a "person belonging, at conception, to the sex that produces the small reproductive cell". McBride, who is the first out trans congresswoman, quipped to The Independent that Trump "just declared everyone a woman from conception based on the language of the executive order". But anyone with a background in biology will know that all human embryos follow a "female" developmental path until the activation of the SRY gene several weeks after conception, which sparks sexual differentiation.
