Question
Chapter 47.3, Problem 4CC
Summary Introduction
To explain: The expected result, when zone of polarizing activity (ZPA) is removed from a limb bud and then a bead dripped in sonic hedgehog is placed in the center of the limb bud.
Concept introduction: The limb bud development is determined by two regions – the apical ectodermal ridge (AER) and the zone of polarizing activity (ZPA). The AER region determines the growth of a limb along the proximal-distal axis. The ZPA region determines the growth of the limb along the anterior-posterior axis.

Drain off excess alcohol from the buds and aseptically excise the anthers from each bud. Remove the filaments and culture the anther on one of the agar media provided. Label the stage of development of the bud on each petri dish as the anthers are cultured. Seal the Petri dishes with parafilm. Incubate in the dark at 26 to 28ºC for 4 to 8 weeks or until small plants can be seen growing out of the anthers. Then transfer to diffuse light. Record the results of the experiment in table form and submit the report. Observation: The culture was contaminated after 8 weeks of incubation…arrow_forward
