I'm not 100% sure what you're talking about here, but this looks like alleles, not genes. For every gene, there is one copy on each of a pair of chromosomes. The gene can take different forms, called alleles. In the "simple" case, there are only two possible alleles - dominant and recessive. When geneticists are analyzing the probability that an offspring will have the trait in question, they use a capital letter to indicate the dominant allele and a lower-case letter to indicate the recessive allele. The letter used is usually somehow representative of the trait. For Example, T (whether upper or lower case) might refer to a gene that has something to do with tongue. But there is no standard set of letters used to designate specific genes in this context. The T and t in this case could represent any gene, though the T clearly represents the dominant allele and the t represents the recessive allele.
By the way, in a simple, one-gene, dominant/recessive case an individual with one Dominant and one Recessive gene (Tt genotype) would have the trait in question, because the dominant allele overrides the recessive one. Only a person with a tt genotype would lack the trait.

Genetics Tt and TT are examples of?
They are examples of a pair of alleles, possibly from the vitamin D receptor gene
What is the combination alleles in purebred tall of pea plant?
Most teachers will designate the dominant gene capital letter. In Mendel's experiment he crossed purebred Tall (T) with purebred short (t). He got all Tall plants as a result. Tall purebreed genotype is TT and the resulting generation was all tall by heterozygous with a genotype of Tt.
In a Punnett square a capital letter stands for a allele.?
Capital letters on Punnett Squares represent dominant genes, while lowercase letters represent recessive genes. For example, if the trait "T" is a tall gene and the trait "t" is a short gene. When you get your results (if both parents are heterozygous for tallness, Tt) you get four possible results, 1 TT (homozygous tall), 2 Tt (twice, heterozygous tall Tt), and 1 tt (homozygous short). If there is a dominant gene there, that gene will be displayed. Only if there are two recessive genes will the recessive trait be displayed.
What is true of the allele pair of someone with a genotype of tt?
The allele pair of someone with a genotype TT is homozygous dominant.
How many alleles does a pea plant gamete have for the height gene?
TT or Tt
Genetics Tt and TT are examples of?
They are examples of a pair of alleles, possibly from the vitamin D receptor gene
What has the Tt genotype?
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.
What does a capital letter such as T represent ina punnet square?
Capital letters on Punnett Squares represent dominant genes, while lowercase letters represent recessive genes. For example, if the trait "T" is a tall gene and the trait "t" is a short gene. When you get your results (if both parents are heterozygous for tallness, Tt) you get four possible results, 1 TT (homozygous tall), 2 Tt (twice, heterozygous tall Tt), and 1 tt (homozygous short). If there is a dominant gene there, that gene will be displayed. Only if there are two recessive genes will the recessive trait be displayed.

What is the relationship between dominant and recessive alleles in a heterozygous organisms?
it means there is one of each. in a homozygous gene it means that there are two of the same. for example if "t" repressents a recessive trait and "T" represents a dominant trait, then an organism with a gene that is tT would be considered heterozygous, and a gene that is TT or tt would be considered homozygous or "pure bred"

What is true of the allele pair of someone with the genotype TT?
The allele pair of someone with a genotype TT is homozygous dominant.

The allele pair of someone with a genotype TT is homozygous dominant.
What are the possible genotypes of pea plants?
Either TT or Tt, where T stands for dominant gene for tallness and t for recessive gene.
How many alleles does a pea plant gamete have for the height gene?
TT or Tt
