Phenotype Information from the receiver is posted in the form of a "researcher : phenotype" lethal or sterile. Dr. M. Han: early larval lethal. Dr. R. Plasterk: homozygous inviable and experiments terminated. Dr. W.G. Kelly: homozygous animals are normal with low level sterility and produce some dead progeny and sterile offspring. Dr.S. Strome: Development 134, 757 (2007).
