In dogs, the gene for fur color has two alleles.  The dominant allele (F) codes for grey fur and the recessive allele (f) codes for black fur. The female dog is heterozygous.  The male dog is homozygous recessive. Predict  the most likely  phenotype ratio and  and genotype ratio  of their possible puppies. 

• 100% black ff

• 100% grey FF

• 50% grey Ff

• 25% grey FF
