[R-sig-ME] lmer vs glmmPQL

Regarding this thread, what about the method of fitting nested models
and using anova() to estimate a p-value.

For example:

mod2 = lmer(y ~ genotype + (1|block), family = binomial, data)
mod0 = lmer(y ~ (1|block), family = binomial, data)


How does that p-value (which is one value for the whole term
"genotype") relate to the individual coefficient p-values derived from
the Z-scores inside summary(mod2)?
