Title Embryo_placenta_weights
Downloaded 13 times
Description 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.

Title Breeding_success
Downloaded 4 times
Description These data are the reproductive output of different crosses. These data are in 4 columns: 1. cross.number: in the form "BB.BB1" Letters represent species ( B=P. campbelli, S=P. sungorus ). The first two letters are the mother's species, the second two letters are the father's species. Further, each unique litter is given a number. 2. mother.number: the unique identification number of the mother. 3. days.to.birth: number of days from crossing to a successful birth. 4. success.preg: 1 if the female gave birth in the first 40 days, 0 if she did not give birth in the first 40 days

Title 10_day_weights
Downloaded 7 times
Description Data for assessing standard growth curves of hamsters from day 10 to day 100. This file includes 5 columns: 1. cross.number: in the form "BB.BB1" Letters represent species ( B=P. campbelli, S=P. sungorus ). The first two letters are the mother's species, the second two letters are the father's species. Further, each unique litter is given a number. Apparent duplicates are due to multiple offspring born to each litter which were not uniquely identified. 2. genes: a description of pure P. campbelli (BB.BB), pure P. sungorus (SS.SS) or the F1 P. campbelli x P. sungorus (BB.SS) 3. age.day: the age each individual was when weighed 4. weight.g: the weight in grams of each individual 5. sex: the gender of each individual. Unknown for young individuals.

Title Hamster_database
Downloaded 7 times
Description Data concerning crossing dates and number of offspring used to assess sex ratio. Data are in 7 columns: 1. cross number: in the form "BB.BB1" Letters represent species ( B=P. campbelli, S=P. sungorus ). The first two letters are the mother's species, the second two letters are the father's species. Further, each unique litter is given a number. 2. mother.number: mother's unique identification number. 3. father.number: father's unique identification number. 4. birthdate: when the litter was born. 5. female.number: number of female offspring in the litter. 6. male.number: number of male offspring in the litter. 7. total.litter.number: sum of males and females in the litter
