Embryo_placenta_weights

These data include the weights of all embryos and placentas as well as other birth defects. These data are in 15 columns: 1. ID: unique Identification number for each individual. In the form BB.BB1.1, the first two letters are the mother's species (BB=P. campbelli, SS=P. sungorus). The second two letters are the father's species. Thus hybrids are designated BB.SS or SS.BB. The first number is the unique litter number and the final number is the individual in that litter. 2. Cross: the unique cross identification number, or the cross each individual was from. 3. Date: date that the mother was sacrificed and the dissection was done. 4. Age: the approximate age that the embryos were in development. day 15-18 are considered "late development". 5. Reabsorbing: 0 if not reabsorbing, 1 if reabsorbing. 6. molar conceptus: 0 if not a molar conceptus, 1 if a molar conceptus. 7. edema: 0 if no edema, 1 if edema was present. 8. photo number: the photo name. 9. gender: sex if known. 10: Genes: a description of pure P. campbelli (BB.BB), pure P. sungorus (SS.SS) or the F1 P. campbelli x P. sungorus (BB.SS). 11: Embryo: embryo weight in grams. 12: Placenta: placenta weight in grams. 13: Individual: the individual in the litter. 14: Mother: mother's unique identification number. 15: Father: father's un ique identification number.
