law of independent assortment b
I think it's genotype...
An individual with a heterozygous genotype cannot be true-bred.
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.
Two: TG and tG
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.
For the case of the human, an individual with XX genotype is female. Other organisms have different ways of determining sex.
