excess pharyngeal cells

Animals contain an excess number of pharyngeal cells compared to control. In C. elegans, pharyngeal cells are derived from MS-blastomere. The overproduction of pharyngeal tissues is a result of other blastomeres adopting an MS-like fate.

extra pharyngeal muscle cells

Animals contain an excess number of pharyngeal muscle cells compared to control. In C. elegans, pharyngeal cells are derived from MS-blastomere. The overproduction of pharyngeal tissues is a result of other blastomeres adopting an MS-like fate.

MS lineage variant

The descendants of the MS blastomere exhibit any variation in developmental programs compared to their counterparts in control animals.

fewer pharyngeal cells

Animals contain fewer pharyngeal cells compared to control animals. In C. elegans, pharyngeal cells are derived from MS-blastomere.

no posterior pharynx

Embryos fail to generate cells that give rise to the posterior portion of the pharynx. In C. elegans, the MS blastomere- derived pharyngeal cells constitute the posterior portion of the pharynx.
