Final answer:
Achondroplasia is a genetic form of dwarfism with autosomal dominant inheritance, caused by a mutation in the FGFR3 gene, resulting in a large head and short limbs.
Step-by-step explanation:
Achondroplasia is a genetic condition that results in short-statured dwarfism characterized by a large head and prominent forehead. This condition is indeed inherited and occurs due to a mutation in the FGFR3 gene. The mode of inheritance for achondroplasia is autosomal dominant, which means that only one copy of the mutated gene is needed for the condition to be expressed. If a person with achondroplasia has children, there is a 50% chance that the child will inherit the condition. Other genetic diseases that follow this pattern of inheritance include Marfan syndrome and Huntington's disease, which indicate the presence of at least one faulty gene that can be passed on to the offspring.
