Answer:

Step-by-step explanation:

If any recessive phenotypic individuals result from the cross, then the unknown individual must carry the recessive allele, and have the heterozygous genotype. A testcross helps reveal the genotype of an organism when that organism shows the dominant trait, such as agouti coat color in rats.
