**Which of the following is an illustration of permissive interaction?****A.** The epidermis signals the underlying dermis to create condensations and the dermal condensations then signal the epidermis to form specific cutaneous structures.**B.** Wing epidermal epithelium produces wing feather when exposed to wing dermal mesenchyme but will produce scales and claw when exposed to foot dermal mesenchyme.**C.** When implanted in the newt embryo, the frog oral ectoderm can only differentiate into frog derivatives and will not differentiate into newt derivatives.**D.** An inducing signal from the optic vesicle is necessary for new gene expression in the lens ectoderm.**E.** Contact with the appropriate extracellular matrix is sufficient for cells to express differentiation-specific genes. ### Understanding Induction in Developmental Biology**Question:** Which of the following is an illustration of induction? (Check all that apply.)**Options:**- **A**: The optic vesicle secretes factors that cause the overlying lens ectoderm to thicken.- **B**: Ectodermal cells secrete growth factors that promote their own proliferation.- **C**: The lens vesicle secretes factors that promote the invagination of the underlying optic vesicle.- **D**: Migrating embryonic cells secrete matrix modifying enzymes.- **E**: Mesodermal cells secrete ECM molecules that promote their own migration.**Explanation:** Induction is a process in embryonic development where one group of cells influences the development of another group through chemical signals. This process is crucial for proper tissue formation and organogenesis.- **Option A** depicts a classic example of induction where the optic vesicle's signaling leads to changes in the lens ectoderm. - **Option B** and **E** describe autocrine signaling mechanisms, not induction, as they involve cells influencing themselves. - **Option C** describes a reversed scenario of A and does not typically illustrate induction. - **Option D** discusses the action of cells modifying their environment, not influencing other cell types.Suitable illustrations for induction should involve interactions between different cell types leading to developmental changes.

Which of the following is an illustration of permissive interaction? The epidermis signals the underlying dermis to create condensations and the dermal condensations then signal the epidermis to form specific cutaneous structures. Wing epidermal epithelium produces wing feather when exposed to wing dermal mesenchyme but will produce scales B and claw when exposed to foot dermal mesenchyme. When implanted in the newt embryo, the frog oral ectoderm can only differentiate into frog derivatives and will not differentiate into newt derivatives. An inducing signal from the optic vesicle is necessary for new gene expression in the lens ectoderm. Contact with the appropriate extracellular matrix is sufficient for cells to express differentiation-specific genes.
