What is the difference between a girl and a man?

The main difference between the sexes lies in the 23 pairs of chromosomes. Females have two X chromosomes, and males have XY chromosomes. This is what determines all the differences between their organisms. Females are usually shorter, with narrow shoulders, short legs and large hips. The female body has a higher percentage of fat. Women’s brains are slightly smaller than men’s. They are characterized by large liver, kidneys and abdomen. The female body performs important functions that are not typical of the male body: menstruation, pregnancy and lactation. Of course, the genitals of these individuals are completely different.
