In certain types of cells, like liver and heart tissues, tetraploid cells are normal and common. However, sometimes the formation of tetraploid cells may be an unintentional result of exposure to chemicals or other factors. These rogue tetraploid cells may eventually lead to tumor formation. These cells most likely form due to a failure at which phase of the cell cycle?

Cytokinesis

Explanation:

Cytokinesis is the last phase in cell division.

It is a well ordered stage, that needs a detailed interaction between cytoskeletal, chromosomal and cell cycle regulatory pathways. An astonishing wide amount of certain cellular activities are also essential for cytokinesis, inclusive of protein and membrane interaction, lipid metabolism, protein synthesis and signaling pathways.

As a largely controlled, complex phase, it is not unforeseeable that cytokinesis often times fail. Cytokinesis failure will cause centrosome amplification and formation of tetraploid cells, which cause the formation of tumor cells. Thou, tetraploid cells are rich components of some typical tissues such as liver and heart, signifying that cytokinesis is physiologically controlled.

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.
