It may be likely - but it is not a logical necessity: there can be large structural differences between functionally equivalent things (artificial, engineered example: like a C64 computer and a C64 emulator)

Being suited to a job is a combination of hundreds of factors e.g. experience, temperament, social skills, personality type. And those factors do not necessarily correlate with gender.

So ignoring all of those factors and just focusing on gender is illogical. Especially given that men/women are not all uniform and exhibit wildly different personality and behavioural traits.

It really depends on the job, doesn't it? If the job is, for example, a dock worker physically lifting heavy crates / boxes all day, is it unreasonable to expect there to be a gender bias in hiring for that position? How about a bouncer at a bar?
