normal sexual cross pollination - each parent plant contributes traits from its genotype (which are expressed as the phenotype)
It depends on the allele combinations of the other pea plant parent. If the other pea plant parent also has a genotype of RrYy, then there are 16 combinations. If the other parent has genotype RRYY, then there are only 4 allele combinations. If the other parent has a genotype of RrYY, then there are 8 allele combinations in the gametes. If the other parent has a genotype of RRYy, then there are also 8 possible combinations in the gametes. Finally, if the other parent has the genotype rryy, then there are 4 gamete combinations.
if we assume tall plant <T> & short plant as< t> genotype of tall plant ; TT genotype of short plant ; tt
The genotype of the tall pea plant is heterozygous

To figure this out, use a Punnet Square.First, set up a test cross, like this:Rr x rrThis shows what you are crossing. Now you can make a Punnet Square.R rr Rr rr There is a 50/50 chance that the corn plant will have thegenotype rr.r Rr rr
TT or Tt
A tall looking pea plant can have a genotype of Tt or TT.
if we assume tall plant <T> & short plant as< t> genotype of tall plant ; TT genotype of short plant ; tt
If gene T is responsible for tallness in a plant, then Tt will be genotype of a heterozygous tall plant.

Because the Tall gene in plants is dominant, a plant that has the genotype Tt (Heterozygous) would be a Tall plant.
Because the Tall gene in plants is dominant, a plant that has the genotype Tt (Heterozygous) would be a Tall plant.
The genotype of the tall pea plant is heterozygous
both must be tt or both must be Tt
