Separationofseaurchinblastomeres
Objective: to separate the Blastomere at different points in development and observe the growth of the resulting embryos.Procedure: We extractrf the gametes from the sea urchins, fertilized the sea urchin eggs, and removed the fertilization envelope. The cells were then be allowed to cleave, at which point they were be introduced into a hypertonic seawater solution. This caused the cells to shrink and break apar......阅读全文
