Chapter 19, Problem 3P

Early C. elegans embryos display mosaic determination, whereas early mouse embryos exhibit regulative determination. Predict the results you would expect if the following treatments were performed on four-cell embryos of each of these two species (assuming these manipulations could actually be performed):

a.	A laser is used to destroy one of the four cells (this technique is called laser ablation).
b.	The four cells of the embryo are separated from each other and allowed to develop.
c.	The cells from two different four-celled embryos are joined together to make an eight-celled embryo.
