DQuestion 9 10 pts Which of the following is correct about the Nematode C. elegans? check all that apply, there is more than one answer. Asymmetrical rotational holoblastic cleavage In C. elegans gametogenesis, carly meioses results in eges while later meloses results in sperms which is stored in the spermatheca The P lineage consists of stem cells that evantually form the germ cols. Cell specihcations and fate is determined autonomously The embryonic germ layers in elegans endoderm, mesoderm and ectoderm, are derived from several founder cels n the early embryo. A cell which gives rise to a specific lineage of cells is a founder coll C elegans was chosen as a model organism because it has a small number of cells, has a small genome casily bred short life span, and can be genetically manipulated The EMS cell is the precursor of the future gut and muscle cells SKN-1. PAL 1. & PIE-1 proteins are cytoplasmic transcription factors Sperm entry determinc DV axis
