Specification (capable of being altered)

It is a labile phase, so it is not fixed.

There are three different modes of cell specification: 

1. Autonomous

2. Conditional

3. Syncytial

Autonomous Specification

Cell “knows” very early what it is to become without interacting with other cells

#Unit 5. Developmental Biology

Autonomously specified cells capable of differentiating autonomously (i.e., by itself) when placed in an environment that is neutral with respect to the developmental pathway.

In Autonomous Specification

Prospective potency is equal to prospective fate.

Autonomous Specification

Produces "mosaic" ("determinative") development 

Cells cannot change fate if a blastomere is lost
