  1. Dnd1KO segregation in intercrosses and backcrosses. Results are presented after pooling data for both genders (Tables 1, 2, 3, 4), because occurrence of females and males did not differ significantly (not shown).
  2. *Mendelian expectations based on Dnd1+/+; litter size (mean ± SEM, n is the number of litters).
