Question

What is cell lineage theory?explain it

Answer 1

Cell lineage denotes the developmental history of a tissue or organ from the fertilized embryo.[1] Cell lineage can be studied by marking a cell (with fluorescent molecules or other traceable markers) and following its progeny after cell division. Some organisms as C. elegans have a predetermined pattern of cell progeny and the adult male will always consist of 1031 cells, this is because cell division in C. elegans is genetically determined and known as eutely.[2][3] This causes the cell lineage and cell fate to be highly correlated. Other organisms, such as humans, have variable lineages and somatic cell numbers.
