Final answer:
Camptodactyly is typically inherited in an autosomal dominant pattern meaning that it is expressed when only one copy of the mutated gene is present on an autosomal chromosome.
Step-by-step explanation:
Camptodactyly follows an autosomal dominant inheritance pattern.
Inheritance patterns describe how traits are passed from parents to offspring. Camptodactyly, characterized by abnormal flexion of the finger joints, is typically inherited in an autosomal dominant manner. This means that only one copy of the altered gene, present on one of the 22 autosomal chromosomes, is sufficient to express the trait.
Unlike discontinuous variation where traits are distinct and transmitted independently, or X-linked recessive patterns relating to the X chromosome, an autosomal dominant trait does not require both parents to pass on the mutated gene for the trait to appear. Although less common, camptodactyly can have other inheritance patterns, including autosomal recessive, depending on the specific genetic circumstances and the family history.
