Figures 2.8 and 11.12 present two different experiments that were designed to test whether amphibian embryos undergo regulative vs. autonomous cell fate specification The figure 2.8 was originally presented as evidence for autonomous cell fate specification What was reasoning behind this conclusion? What was different about the experiment presented in figure 11.12? Is development in amphibians regulative, autonomous, or a combination of the two? Explain your reasoning. Describe an experiment that would test the hypothesis that a specific cell fate decision was cell autonomous. Describe one outcome that would support your hypothesis. Describe one outcome that would not support your hypothesis.

Solution

9)It is a combinations of regulative and autonomous as the indivisual units divide making them autonomous and independant and they are directed in step by step procedure to create an embryo making it regulative as well.

10)The experiment would include to check if the cell divides or not into other units.If the cell divided then it is not autonomous otherwise it stays independant and autonomous.

The one outcome supporting is that fertilisation takes place and produced different embryo and the outcome that doesnt support is when fertilization produces 2 embryo connected to each other not indivisual.
