For each assay at least 12 embryos were assayed.

SD is Standard Deviation

The p value was < .001 for metaphase plate length and metaphase spindle perimeter measurements for embryos exposed to 6 or more hours of anoxia and for metaphase plate width measurements for embryos exposed to 12 hours of anoxia.
