What are the genotypes of a dominant tall pea plant to short pea plants?

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).

∙ 11y agoThe 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).

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
In the P generation a tall plant was crossed with a short plant No F1 plants were short Short plants reappeared in the F2 generation because?
A cross between members of the F1 generation (Tt x Tt), results in the genotypic ratio of 1TT:2Tt:1tt genotypes in the F2 generation. Because the tall allele is dominant, the phenotypic ratio would be 3 tall:1 short in the F2 generation.
What size pea plants would result when two short plants are crossed?
I think you're talking about Mendel's famous pea plant study. It's not the size that matters, but rather the genotype. The parents have to possess a certain pair of chromosomes to create a specific phenotype (short plants).Here's your answer:Let's use T to represent the dominant trait of tallness, and t to represent a recessive trait of shortness.If both parents are short plants, their genotype would have to be tt (dominant could be TT or Tt). So when you crossed their chromosomes for offspring, their genotypes would also be tt. Therefore, the phenotype would be short.
What type dominance do pea plants show?
The recessiive trait one is 50%,dominant is 75% or above.
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 tall (T) plants are dominant over short (t) plants. If a heterozygous (Tt) pea plant is crossed with a homozygous dominant (TT) pea plant all of the resulting pea plants should be tall (?
Dominant Allele
How can two plants that have different genotype have the same phenotype?
No they do not. Say for example we are looking at the the colour of pea plants where R represents the allele for the colour red and, and the other allele r represents green. The plant will be red with the genotype RR AND Rr which are different genotypes.
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
In certain plants tall is dominant to short If a heterozygous plant is crossed with a homozygous tall plant what is the probability that the offspring will be short?
0 (there is no chance it will be short since tall is dominant over short). Hope this helps! - Biology Student
What is the symbol for the genotype of true breeding tall plants short is Dominant?
if we assume tall plant <T> & short plant as< t> genotype of tall plant ; TT genotype of short plant ; tt
In the p generation a tall plant was crossed with a short plant. Short plants reappeared in the f2 generation because?
A cross between members of the F1 generation (Tt x Tt), results in the genotypic ratio of 1TT:2Tt:1tt genotypes in the F2 generation. Because the tall allele is dominant, the phenotypic ratio would be 3 tall:1 short in the F2 generation.
A tall pea plant and a short pea plant produce short offspring this is an example of?
This was an example of tallness being a dominant phenotypic trait in pea plants
Why isn't it possible to have more genotypes than phenotypes?
I think you have the question backwards, "Why isn't it possible to have more phenotypes than genotypes?" There are always more or an equal number of genotypes relative to phenotypes. The phenotype for a simple dominant/recessive interaction (for example) T for tall and t for short where TT is tall, Tt is tall and tt is short has three genotypes and two phenotypes. If T and t are co-dominant then TT would be tall, Tt would be intermediate and tt would be short. (Three phenotypes and three genotypes.)
In the P generation a tall plant was crossed with a short plant No F1 plants were short Short plants reappeared in the F2 generation because?
A cross between members of the F1 generation (Tt x Tt), results in the genotypic ratio of 1TT:2Tt:1tt genotypes in the F2 generation. Because the tall allele is dominant, the phenotypic ratio would be 3 tall:1 short in the F2 generation.
In poppies tall is dominant over short and red is dominant over white If two plants of genotypes ttRr and TtRR were crossed and no mutations occuredwhat is the percentage of short white plants in F1?
Your F1 generation has 0% of short, white plants. Anything crossed with TtRR wil have at least one R = red. Possible alleles of plant ttRr: tR and tr (on the horizontal) Possible alleles of plant TtRR: TR and tR (on the vertical) Using a Punnett's Square: tR tr TR TtRR TtRr tR ttRR ttRr TtRR = Tall, Red TtRr = Tall, Red ttRR = Short, Red ttRr = Short, Red So, as you can see, all of the possibilities have at least one R, so they will all be red, since R is dominant.

What happened when Gregor Mendel crossed a tall plant with a short plant?
When Gregor Mindel crossed homozygous tall plants with homozygous short plants,he got hetrozygous tall plants. Tall plants will dominate any small pea plants in the same area.The traits for tall were dominant over short traits. Perhaps both alleles can code for protein, but the dominant product is expressed in the phenotype.
