I think it's genotype...
An individual with a heterozygous genotype cannot be true-bred.
Two: TG and tG
If an individual is of the dominant phenotype, its genotype can be either AA or Aa (letter A picked for demonstration's sake). To do a good test cross, we have to be able to unambiguously tell which one of the genotypes the individual is. The best test cross would be conducted with a homozygous recessive (aa) individual. This way, if the cross generates 100% dominant phenotype, then the original individual was homozygous dominant. If the cross generates 50% dominant and 50% recessive phenotype, then the original individual was heterozygous.
For the case of the human, an individual with XX genotype is female. Other organisms have different ways of determining sex.
Only one; A. At least concerning this one trait.

Dd is the heterozygous genotype for dimples.

The term allele is different from a genotype because an allele can be singular, but the alleles that an individual (diploid organism) has at a certain locus are called a genotype.
Genotype is the alleles (different forms of a gene) which an individual has with respect to a particular characteristic. The Phenotype is how these genes are expressed in an individual.
