What type of inheritance is achondroplasia?

Answer 1

Achondroplasia is inherited by the parents as a dominant disease. It occurs from a defect in the FGFR3 gene. It usually occurs spontaneously. if both parents have the disease they have a 25% chance of having a normal sized child, a 50% chance of having a child with Achondroplasia, and a 25% chance of the child getting both genes from each parent which results in death.
