The expectations from heterozygous bob-tail x normal tail crosses. Half the puppies should have bob-tails
and half will have normal tails. Half-shaded boxes indicate the bob-tail heterozygotes (Bob/+) and the open boxes those
with the normal long tail (+/+).
The expectations from intercrosses of bob-tail heterozygotes. 75 percent of the progeny should have bob-tails
- if the homozygotes are born and resemble the heterozygotes; the homozygote should comprise 33 percent, or 1/3, of those puppies with bob-tails. The bob-tail homozygotes (Bob/Bob)
are indicated by fully-shaded boxes.
The expectations from homozygous bob-tail x normal tail crosses. All the puppies should have bob-tails.
