Q

How does epigenesis work?

A

The theory that an embryo develops progressively from an undifferentiated egg cell.

Mosaic Development:
Cell division divides egg into parts of different potential

Regulative development:
Communication between cells instructs development
-complexity gradually emerges
-cell sends signals to determine where they are

2
Q

Mosaic or regulative development?

A

Both occur.

Usually start with some mosaic, then use cell communication.

3
Q

A

Morphogens - different concentrations of same molecule give different information.
