Why are people born midgets?

People are born with dwarfism, commonly referred to as being a "midget," due to genetic factors that affect bone growth and development. The most common form, achondroplasia, is caused by a mutation in the FGFR3 gene. Other types of dwarfism can result from different genetic conditions or medical issues during fetal development. Overall, dwarfism is a complex trait influenced by various genetic and environmental factors.
