Table 2. Bone volume summary statistics at embryonic day 17.5 (E17.5) and postnatal day 0 (P0) for Fgfr2cC342Y/+ mice and their Fgfr2c+/+ littermates.
Sample size (N) varied by availability of individual bone for analysis. Interfrontal and ethmoid bones develop relatively late and were not present in many specimens.
