Question

What are the two ways that cell fate is determined in embryonic cells?

a.Name one similarity between the two.

b.Name one difference between the two.

Answer 1

Cell fate determination. Within the field of developmental biology, one goal is to understand how a particular cell develops into a final cell type, known as fate determination

two ways that cell fate is determined in embryonic cells

• autonomous specification
• conditional specification

Autonomous cell specification ( m0osaic development ) is a form of specification in which the developing cell is able to differentiate (express proteins typical of the mature cell) without receiving external signals.

Oocyte factors - morphogenetic determinants

Conditional specification ( regulative development )  is the type of specification is a cell-extrinsic process that relies on cues and interactions between cells or from concentration-gradients of morphogens.
