Foster Feeding Experiment


The data are from a foster feeding experiment with rat mothers and litters of four different genotypes. The measurement is the litter weight after a trial feeding period.




A data frame with 61 observations on the following 3 variables.


genotype of the litter, a factor with levels A, B, I, and J.


genotype of the mother, a factor with levels A, B, I, and J.


the weight of the litter after a feeding period.


Here the interest lies in uncovering the effect of genotype of mother and litter on litter weight.
