Molecular Biology of the Cell. The proportion of cell lines within a bin 0. The Y chromosome does include some male sex genes, but it doesn't exactly determine sex. Further research is therefore needed to investigate whether changes occur to the chromosomes of cancer cells growing within the body, and whether this gives them an advantage over normal cells.

June Still, even in the latter, random choice is not an infallible process and several cases of non random selection have been described, with a possible link to the onset of various diseases. However, the mechanism still remains unclear. In contrast to the morphogen gradient model, multiple chemical signals are required to create the pattern.

It is perhaps the smallest gene occupying only 14 base pairs. Finally, after the 13th division, cell membranes slowly invaginate, dividing the syncytium into individual somatic cells. Methods Details on the fly strains and antibodies used in this study, as well as how xio clones were generated and how Xio antibody was generated, can be found in SI Methods.
