Developmental arrest has no apparent effect on subsequent embryogenesis.

a. Embryos incubated for 6 days at of 37deg.C.

b. Embryos incubated for 10 days at of 37deg.C. Embryos on left were arrested at 15.5deg.C for 6 days prior to incubation at 37deg.C and appear nearly identical to non-arrested embryos shown on right. Morphological features are detailed in the text.
