Ter is a spontaneous mutation in the Dnd1 gene (Youngren et al. 2005). Reciprocal crosses were made between Apobec1 targeted deficiency mutation (m) and Dnd1^Ter. Crosses are presented as “female × male.” “No. Obs” is number observed for each genotype and cross. “% Obs” is the percentage for that genotype among all offspring for each cross. For two segregating genes in these intercrosses, a 1:1:1:1 Mendelian ratio is expected. Results are from Nelson et al. (2012).
