Question
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.
