It is a mating in which an individual showing a dominant phenotype is crossed with an individual showing its recessive phenotype. In a test cross, the unknown individual must be of a dominant phenotype because if the phenotype is recessive the genotype will have to be homozygous recessive.
People just don't care anymore about what they do.
The only possible phenotype is large ears.
This is because using a punnet square reveals that each option has a dominant allele of large ears, leaving no room for the recessive trait of small ears.
