Initial Characterization of ts Embryonic Defective (emb) Mutants

[See Figure 1]
Already published allelism: Wood et al., 1980: b117=b189; b246 = let-
2.Miwa et al., 1980: hc57 = hc62; hc61 = hc67.
Our global complementation results: g1 = g4; g16 = g65 = hc61 = hc67;
g36 = hc65; g23 = g34 = hc70 = b117 = b189; g37 = b246 = let-2; b84 = 
hc66; g14 = g43; g57 = b1O.  From frequency of multiple alleles we 
estimate 200-400 genes essential for embryogenesis.  Mapping is in 
progress.  We are also doing tsp's, R + H Tests, and cellular defects (
Isnenghi, Cassada, Radnia, Schierenberg, K.  Smith, v.  Ehrenstein).
