Draw a punnet square.
Determine the genotype ratio using the formula homozygous dominant: heterozygous: homozygous recessive.
Genotype ratio: 2:2:0 (2:2) or 50%:50%
Determine the phenotype ratio using dominant alleles: recessive alleles.
Phenotype ratio: 3:0 (3 (3/1=3)) or 75%
In conclusion to all of this, there is a 100% probability of a black-furred rabbit.
