Under what conditions would a test cross be performed? When an organism with the dominant phenotype has an unknown genotype. When trying to determine the outcome of a trihybrid cross. When an organism with the recessive phenotype has an unknown genotype. When an organism has a known genotype but unknown phenotype.

In guinea pigs, a black coat (B) is dominant over a white coat (b), and straight hair (S) is dominant over curly hair (s). The genes for coat color and type of hair are located on different chromosomes. A heterozygous, black, and straight hair guinea pig (BbSs) was test crossed. What is the phenotypic ratio of the offspring produced from the test cross? Use 0 for phenotypes not produced in the above cross.
