|
Morulation
|
|
Blastulation
|
|
Gastrulation
|
|
Blastomeres
|
Explanation:
Detailed explanation-1: -Labeling individual cells within their germ layers allows for a pictorial interpretation of gastrulation. This chart or graphical representation detailing the fate of each part of an early embryo is referred to as a fate map. In essence, each fate map portrays the developmental history of each cell.
Detailed explanation-2: -Genetic information can also be used to generate a fate map. Genetic fate mapping (GFM) uses two genetically engineered alleles, one of which expresses a site-specific recombinase, such as cyclization (Cre) or flipase (Flp), while the other contains a reporter allele such as green fluorescent protein (GFP).
