Inheritance of tuft/tuft postnatally based on outcross to BALB/c.
| Cross | Total # of offspring | # affected | % affected | % expected if recessive | total # of litters |
|---|---|---|---|---|---|
| 3H1 tu/tu × 3H1 tu/tu (INC) | 140 | 32 | 23 | 100 | 39 |
| 3H1 tu/tu × BALB +/+ (OC) | 55 | 0* | 0* | 0 | 15 |
| 3H1 tu/tu × 3H1×BALB tu/+ (BC) | 359 | 36 | 10 | 50 | 70 |
