a
Maternal characteristics include the strain of the dams and the parental origin (maternal/paternal) of the dams' Rb chromosome.
b
Paternal characteristics include the strain of the sires and the parental origin (maternal/paternal) of the sires' Rb chromosome.
c
Maternal transmissions provide the count of offspring that inherited the Rb or the normal chromosome from a Rb heterozygous dam.
d
Paternal transmissions provide the count of offspring that inherited the Rb or the normal chromosome from a Rb heterozygous sire.
