Fig. 7. PIG-1 acts cell-autonomously to regulate the asymmetric division of the
Q.p neuroblast. The numbers of AVM and PVM neurons were scored using
zdIs5 [mec-4::gfp]; the number of lineages scored is shown
in parentheses. Expression of pig-1 from the mab-5 promoter
does not rescue the extra AVM phenotype of pig-1(gm344) but does
rescue the extra PVM phenotype. Statistical analysis was performed using a
one-tailed two-sample Z-test (using the normal approximation to the
binomial distribution) by the StatCrunch program
(www.statcrunch.com).
