XX chromosomes make the female unique. They have ovaries producing haploid DNA cells we call eggs. They have a uterus in which said egg can become a human being after conception. They can carry a fertilized egg to full term human being and subsequently feed the baby 100% from her own body which produces milk from mammary glands. They are the sole reason why most high school boys hold a job so they can buy a car and engage in the mating rituals of young homo sapien males engage in across the fruited plane. I learned that at UCF in genetics and mammology . The female of our species hold the ability to create,carry ,deliver, nurish and lead the next generation humans. it's actually quite spectacular if you ask me. They are the gate keepers of the miracle we call life.
women also have less muscle mass. they have more body fat. Their pelvis is wider too. other than that they are regular people.
