You can perform test crosses with individuals of known genotypes and analyse the offspring you get.

The allele pair Tt is used to represent an individual who has a dominant heterozygous genotype for tallness. The dominant gene but not the recessive gene is physically manifested.
A heterozygous genotype includes two different alleles.
Are you talking about phenotype or genotype? Phenotype is the expression of the genotype. Genotype is what you inherited. Phenotype is what you see. Homozygous is the same. Heterozygous is different. If you inherit one allele for blue eyes and one allele for brown eyes, your phenotype should be brown eyes. Your genotype would be brown eyes, blue eyes. You would have a heterozygous genotype.
AaBb usually, but can also be AAbb or aaBB depending on what they ask you is heterozygous. To be heterozygous for one trait, it's AaBb. To have a heterozygous genotype, unless specified, it can be any of the above.
Dd is the heterozygous genotype for dimples.
An individual with a heterozygous genotype cannot be true-bred.
Heterozygous.
n genetics, a test cross, first introduced by Gregor Mendel, is used to determine if an individual exhibiting a dominant trait is homozygous or heterozygous for that trait. More simply put, test crosses determine the genotype of an individual with a dominant phenotype.
To determine the genotype of an individual that shows the dominant phenotype you would cross that individual with one that is homozygous recessive. A monohybrid cross of two individuals that are heterozygous for a trait exhibiting complete dominance would probably result in a phenotype ratio is 3 dominant 1 recessive.

Heterozygous
The allele pair Tt is used to represent an individual who has a dominant heterozygous genotype for tallness. The dominant gene but not the recessive gene is physically manifested.
A heterozygous genotype includes two different alleles.
A heterozygous genotype
A Heterozygous genotype means an organism that has both the dominant and the recessive gene.
