Based on this information, what is Dallas's phenotype for the coat color trait?

 - a red coat
 - a black coat
You need to determine Dallas's phenotype for the coat color trait. First, consider the alleles in Dallas's genotype for the coat color gene. Then, decide whether these alleles are dominant or recessive.
The allele for a red coat (l) is recessive to the allele for a black coat (L). This means L is a dominant allele, and l is a recessive allele.
Dallas's genotype of Ll has one dominant allele and one recessive allele. An organism with at least one dominant allele for a gene will have the dominant allele's version of the trait. So, Dallas's phenotype for the coat color trait must be a black coat.
