Sequence in the development of fetal morphological characteristics.

Fetal morphological characteristics illustrated by the range of 95% of the observations within each group of categorical variables for 247 Holstein fetuses. For the lower (left) group, the 95% is from minimum to the 95-percentile. For the upper (right) group, the 95% cover the 5th percentile to maximum, and for the remaining groups covers the 2.5- to 97.5-percentile range.
