Yes. Typically males are more vibrant to draw predators away from females (at least while the females are cardyings eggs but it changes depending on species)
But like... Imagine if people had this... Like on one side they have curves and a single boob. beard grows on half the face. Puberty would be a shitshow.
Yes this happens. In humans it's not usually truly 1/2 female 1/2 Male, its usually closer to one than the other.
However very close to half is possible. I knew a woman who was born so close to half that which sex she was legally considered changed multiple times during her childhood due to changing guidelines.
Most of the time when this happens parents make a decision as to what gender the child will present themselves as and then kids sort of deal with it or decide otherwise later. Apparently this is a lot more complicated when you are in and out of gender specific group homes while your biological sex gets redefined for you.
Anyway, nowadays children usually have surgeries when they are babies that make them more completely the sex they most resemble.
this is a thing, extremely rare but there has been cases where they appear female, but soon after they hit puberty they become pregnant over and over again, their male and female organs continuing this until they get the male components surgically removed. Like one in 500 million rare, if not more
