D)development of vestigial structures
E)brain development

Question

Quizplus · Accepted Answer

Variations in the timing of master gene expression during embryonic development in vertebrates are responsible for differences in adult body form. This is because master genes are responsible for regulating the expression of other genes involved in the development of specific body structures and organs. Differences in the timing of master gene expression can lead to differences in the development of these structures and therefore result in variations in body form.
