No, It is not possible. The trait Tall is always dominant over dwarf.
The dominant trait for height in a pea plant is tall (TT or Tt). The only instance in which a pea plant will be short is if it carries both recessive alleles (tt).
Because the shot gene in the pea plant is a recessive trait, there is only one possible genotype for it: tt
Really, there is no set letter for any allele. It is common, however, to use the first letter of the dominant allele. Since tall height is dominant over short height in pea plants, then the allele for short would be the t (a lowercase t).
OK first, you don't say tT. The dominant allele is always put first. So this would actually be TT Tt Tt and tt. The only way a recessive trait will show is if the dominant trait isn't present. Therefore 3 will be tall and one will be short. BTW: TT isn't an example of an allele. It's actually the genotype. T is an example of an allele. Tallness is a genetic trait, but T is not. A genetic trait is simply a title that includes whatever phenotype may become apparent. A phenotype is the trait that shows up. If a person's genotype is TT or Tt, their phenotype will be tall. If a person's genotype is tt, then their phenotype will be short.
Let T=trait (dominant) Let t= trait (recessive) Father has Tt and mother also has Tt The possible combinations for offspring are: TT Tt Tt and tt Therefore There is a 3/4 change of the offspring having the dominant trait and a 1/4 Chance of the offspring having the recessive trait It should also be noted that there is a 1/4 chance of the offspring carrying two dominant genes meaning that any of their children will also share the dominant trait
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.

TT or Tt
No, the short pea trait is recessive and the tall pea plant trait is dominant. This means that if the plant is a hybrid, it has to be a tall pea plant. The dominant traits "mask" the recessive traits. The plant take one trait from their mom and one from their dad. If either the mom or the dad was not a tall, not hybrid pea plant then their kids would have to be tall be cause they would have one dominant, tall trait
