Final answer:
The question refers to normal cranial suture closure in adults, which varies between males and females. Transition analysis is the method used to estimate adult age from skeletal markers like cranial sutures.
Step-by-step explanation:
The suture mentioned in the question is likely one of the major sutures in the human skull, which closes as adults reach a certain age. The process of such suture closures can be observed in studies that focus on craniosynostosis, an abnormal condition characterized by the premature closure of sutures. This leads to various complications due to defective ossification or failure of brain enlargement. In most adults, cranial suture closure is part of the normal aging process and can be analyzed using a method known as transition analysis. This method estimates skeletal age through indicators such as the pubic symphysis, iliac auricular surface, and cranial suture closure. While craniosynostosis is a distinct pathological condition, normal suture closure occurs as a part of the aging process differentially in males and females.
