Question

Longer hindlimbs in crickets appear to result from what type of perturbation to a patterning network?

1) blocked pathway
2) change in signal level of pathway element
3) deployment of a patterning pathway in a new location
4) deployment of a patterning pathway at a new time

Answer 1

Longer hindlimbs in crickets are most likely caused by a 2) change in signal level of a pathway element within the development patterning network.

Step-by-step explanation:

Longer hindlimbs in crickets appear to result from a change in signal level of pathway element, which influences the development process. When considering a patterning network, which is a complex of regulatory signals that guide the growth and development of organismal traits, adjustments in these signals can lead to variations in physical attributes. In the context of cricket development, the hindlimbs are subject to such patterning networks. If the signaling involves the Wnt pathway, for example, fluctuations in signal strength could result in varying limb lengths.
