Either TT or Tt, where T stands for dominant gene for tallness and t for recessive gene.
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.
the tall plant must be heterozygous
Because the shot gene in the pea plant is a recessive trait, there is only one possible genotype for it: tt
Tt
The possible genotypes for blood type A are AA and AO.

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.

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
2 with a punnent square combination of both parents. this is only for the flower genome.
In pea plants, the yellow color (Y) is typically dominant over the green color (y). If a heterozygous yellow pea plant (Yy) is crossed with a green pea plant (yy), the possible genotypes of the offspring would be 50% heterozygous yellow (Yy) and 50% homozygous green (yy). Therefore, the offspring would exhibit a 50% chance of being yellow and a 50% chance of being green.
Either TT or Tt, where T stands for dominant gene for tallness and t for recessive gene.
When a homozygous dominant pea plant (TT) is crossed with a heterozygous pea plant (Tt), the possible genotypes of the offspring are TT and Tt. This results in a 1:1 ratio of tall (TT and Tt) to short (tt) plants. Therefore, out of 200 seeds produced, approximately 200 seeds will be tall plants (100 TT and 100 Tt) and 0 seeds will be short (tt).
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.
both must be tt or both must be Tt
