Either TT or Tt, where T stands for dominant gene for tallness and t for recessive gene.
The possible genotypes of a pea plant include homozygous dominant (BB), homozygous recessive (bb), and heterozygous (Bb) for a single gene trait. This represents the possible combinations of alleles from both parents.
There are many possible genotypes in pea plants, though when referring to Biology, the biologist Mendel studied the following genotypes:
Height:
Tall: TT or Tt
Short: tt
Flower Color:
Purple: PP or Pp
White: pp
Flower Position:
Axial: AA or Aa
Terminal: aa
Pod Color:
Green: GG or Gg
Yellow: gg
Pod Shape:
Inflated: II or Ii
Constricted: ii
Pea Color:
Yellow: YY or Yy
Green: yy
Pea Shape:
Round: RR or Rr
Wrinkled: rr
With all of the above, the possible genotypes are listed with the dominant trait first (Being either Homozygous (both capital letters) or heterozygous (one capital, one lower case letter)) and the recessive trait being second.
A pea plant can carry any combination of those different traits that will effect how the plant looks:
For example:
TTPPAAGGIIYYRR would be homozygous (dominant) for all of the traits, therefore making it a pea plant that had: Tall stem, purple/axial flowers, green/inflated pod and Yellow/round peas inside.
and a:
ttppaaggiiyyrr would be homozygous (recessive) for all the traits, therefore making it a pea plant that had: Short stem, white/terminal flowers, yellow/constricted pod and green/wrinkled peas.
But, of course you can mix and match these and get any number of different kinds of plants.
Because both the Purple gene & the Round gene are both dominant genes, there are two ways they can be expressed:
PP or Pp
RR or Rr
Taking that into consideration, there are four different combinations that will give you purple flowers with round seeds, which are:
PPRR
PPRr
PpRR
PpRr

A pea plant has a tall stem what are its possible genotypes-?
Is tall dominant? You didn't say. Let's assume it is. Therefore, as long as a dominant allele is one of the two alleles an organism has for every trait, and we let "R" stand for dominant tall and 'r' stand for recessive short, then either an RR or Rr genotype will result in a tall phenotype.
In pea plants the allele for tallness is dominant. What are the possible genotypes of a tall pea plant?
the tall plant must be heterozygous
What are the genotypes of the short plants in P1 and F2 Generations?
Because the shot gene in the pea plant is a recessive trait, there is only one possible genotype for it: tt
A testcross on a tall pea plant produces only tall offspring. What is the genotype of the tall pea plant?
Tt
You are looking at four tall pea plants What are their phenotypes and genotypes?
The tall pea plants have the phenotype of tall height. Their genotypes can vary depending on whether they are homozygous dominant (TT) or heterozygous (Tt) for the tall trait.
In pea plants the allele for a tallness is dominant what are the possible genotypes of a tall pea plant?
TT or Tt

What do the letters on the inside of the punnets square stand for?
Using Punnett Squares, you can predict the genotypes and phenotypes of the offspring of a cross between a homozygous (purebred) tall pea plant and a homozygous (purebred) short pea plant.
What do the letters on the inside of the punnet square stands for?
Using Punnett Squares, you can predict the genotypes and phenotypes of the offspring of a cross between a homozygous (purebred) tall pea plant and a homozygous (purebred) short pea plant.
WHAT DO THE LETTERS ON INSIDE OF THE PUNNET SQUARE STAND FOR?
Using Punnett Squares, you can predict the genotypes and phenotypes of the offspring of a cross between a homozygous (purebred) tall pea plant and a homozygous (purebred) short pea plant.
What are three types of genotypes that exist for pea plant height?
Three types of genotypes that exist for pea plant height are: TT - Homozygous dominant genotype for tall height Tt - Heterozygous genotype for tall height tt - Homozygous recessive genotype for short height
How many genotypes does a pea plant with purple flowers have?
2 with a punnent square combination of both parents. this is only for the flower genome.
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 do you find possible phenotypes in offspring?
The possible genotypes and phenotypes of the offspring can be determined using a Punnett square, a grid that shows the possible combinations of alleles that can result at fertilisation. The Punnett square below shows the expected genotypes of the offspring of parent pea plants that both have the genotype Rr.
To produce pea plants that only display the recessive phenotype of trait what must be genotypes of the parent plant?
both must be tt or both must be Tt
In pea plants the allele for tallness is dominant. What are the possible genotypes of a tall pea plant?
the tall plant must be heterozygous
What are the genotypes of the short plants in P1 and F2 Generations?
Because the shot gene in the pea plant is a recessive trait, there is only one possible genotype for it: tt
