How do dwarfs occur?

Dwarfs, or individuals with dwarfism, typically occur due to genetic mutations affecting growth and development. The most common form, achondroplasia, results from a mutation in the FGFR3 gene, which regulates bone growth. Other types of dwarfism can arise from hormonal deficiencies or other genetic conditions. Overall, dwarfism can be caused by a variety of factors, often manifesting in reduced height and other physical characteristics.
