They are examples of a pair of alleles, possibly from the vitamin D receptor gene
Nope! TT is the dominant phenotype (what ever it may be) and tt is the recessive phenotype (what ever that may be).So say T is the allele for Tall plants, t is the allele for short plants. TT would be show the tall phenotype while tt would show the short phenotype. If the genotype was Tt, the phenotype would be tall as well because the T is dominant and masks the phenotype of t (short plants).
The possible offspring outcomes of this cross would be 50% Tt (heterozygous) and 50% tt (homozygous recessive).
The offspring will have a 25% chance of being TT (homozygous dominant), a 50% chance of being Tt (heterozygous), and a 25% chance of being tt (homozygous recessive). This follows Mendel's law of segregation where alleles for a trait separate during gamete formation.
These are letters assigned to alleles or variations in genes. TT means that there are two dominate alleles. Tt means that there is one dominate and one recessive and tt means that both are recessive.
The combination that will complete the Punnett square for this example is Tt. This would be the offspring resulting from a cross between the parent genotypes TT and Tt.
tt in genetics is representing a trait that is homozygous recessive. This is shown through the lower case t's and them both being the same.

Tt, tt -- novanet :)

rather TT Tt tt
TT Tt tt
Tt X Tt Statistically, 1 TT Homozygous dominant, expresses T. 2 Tt Heterozygous dominant, expresses T. 1 tt Homozygous recessive, expresses t.
