Answer:

50%

Explanation:

Both parent's genotype is Bb because they are hairless and alive.

If it has a homozygous dominant genotype (BB), the dog will die in utero.

If it has a heterozygous genotype (Bb), the dog will be hairless but won't die.

If it has a homozygous dominant genotype (bb), the dog will have hair.

The ratio of BB:Bb:bb is 1:2:1 meaning that there is a 50% probability of having a live hairless puppy.

Hope this helps! <3
