Girls typically have 24 ribs, or 12 pairs, just like boys and men. The idea that women have more ribs than men is a common misconception stemming from the biblical story of Adam and Eve.
While the standard number of ribs is 24 for both sexes, there can be variations in the number of ribs due to congenital conditions. Some individuals may have supernumerary ribs (extra ribs), most commonly cervical ribs located near the neck. Others may be missing a rib or have fused ribs. However, these variations occur independently of sex and are relatively rare.
Therefore, assuming no congenital abnormalities, girls and women generally have 24 ribs.
