E)morphogenesis.

Question

Quizplus · Accepted Answer

Apoptosis, or programmed cell death, is the process by which unwanted or unnecessary cells are eliminated during development. In the case of syndactyly, the cells in the webbing between the fingers/toes do not undergo apoptosis, leading to the abnormality. After birth, surgery can be used to correct the condition by separating the affected digits. Differentiation, gastrulation, convergent extension, and morphogenesis are all normal developmental processes that occur in utero and are not directly related to the development of syndactyly.
