Answer 1

Following the characteristic of the gene, the genotypes for spotted dog breeds would be bb.

Genotypes

These are the genes that condition traits.

A gene is made of two alleles. If the alleles for a gene are the same, the gene is said to be homzygous, otherwise, it is heterozygous.

Dominant alleles always mask the effects of recessive alleles whenever they occur together.

Thus, for the trait in question, B_ will always give spotted phenotypes. The only way the recessive allele can be expressed is if they occur together as bb.
