If homozygous tall pea plant and a homozygous short pea plant are crossed?

The resulting offspring will be 25% tall homozygous, 25% short homozygous, or 50% heterozygous. Depending on the gene, the heterozygous will either have codominance, incomplete dominance, normal dominance depending on which gene is dominantly expressed.

∙ 11y agoput TT on top of the box then put tt on the side and divide the box into 4 pieces then the top left box with be TT and the top right will be Tt and the bottom left will be Tt and the bottom right will be tt then it will be 75% tall and 25% short

∙ 13y agoYou will get plants whose phenotype, or appearance, is tall, but whose genotype, or genetic makeup, has one tall gene and one short gene. If T=tall and t=short, all of the resulting plants will have the genotype Tt. They appear to be tall because the tall gene is dominant over the short gene, but can still pass the short gene on if they are crossed with other pea plants.

all offspring will be Tt (heterozygous) genotype and tall phenotype

because T is dominant over t!.....

What is the height of the f1 plant if the tall plant AABBCC is crossed with a base height plant aabbcc?
In such a cross, the F1 plants will always be tall, because that is the dominant allele. In the cross described, a homozygous dominant plant was crossed with a homozygous recessive plant; a cross that produces 100% heterozygous offspring. (AaBbCc)
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 offspring would you get if you cross a homozygous tall plant with a homozygous short plant?
Homozygous dominant would be all Capital letters. Homozygous recessive would be all lower case letters. So...in basic color genetics for horses: A homozygous recessive horse would be aaee A homozygous dominant horse would be AAEE
What kind of offspring will a homozygous tall plant and a homozygous short plant have?
Presuming tall is a dominant allele (the 2nd parent is heterozygous and "tall" is it's phenotype), then the square would be as follows: Let T be the dominant gene for tall, and thus every genotype containing this (TT, or Tt) would produce a tall plant. Let t be recessive, and in the absence of T (tt) causes a plant to be small. So the homozygous tall parent would be TT, and the heterozygous tall parent would be Tt. So now you just have to cross them. During meiosis, every gamete from the TT genotype would contain a T allele. However, for the Tt genotype, there is equal chance each gamete will contain EITHER a T or a t. So the square would be: xxTxxT TxTTxTT txTtxTt As you can see, 2 out of the 4 offspring have a Tt genotype (heterozygous), so this translates to a 1/2 fraction, or 50%. Ignore the Xs in the table- if i just used spaces then all the letters crunched up on top of each other when i pressed save...it was the best i could do...:S
What offspring is produced if a heterozygous n tall pea plant is crossed with a homozygousfor this trait what percent of the offspring will be heterozygous?
If a heterozygous tall pea plant, Aa, is crossed with a homozygous plant, AA, for the trait, you will have a one in one in four chance of the offspring being heterozygous. You will need to create a square and plug the traits in to see what the odds are.
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 height of the f1 plant if the tall plant AABBCC is crossed with a base height plant aabbcc?
In such a cross, the F1 plants will always be tall, because that is the dominant allele. In the cross described, a homozygous dominant plant was crossed with a homozygous recessive plant; a cross that produces 100% heterozygous offspring. (AaBbCc)
5 An F1 plant that is homozygous for shortness is crossed with a heterozygous F1 plant What is the probability that a seed from the cross will produce a tall plant?
there is a 50% chance that the offspring will be tall.
If a homozygous tall and short pea plant are crossed will the offspring be of medium height?
Not if either trait is dominant. Let us say tall is dominant ( I think it is ) and short is recessive. T = tall, and s = short. TT X ss will give heterozygous tall plants. Ts
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
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
When model crossed true-breeding tall plants with true-breeding short plants all of the offspring were tall because?
Homozygous for tall is TT Homozygous for short is tt All F1 offspring from this cross are Tt which makes them genotypically heterozygous and phenotypically tall.
When gregor mendel crossed a tall plant with a short plant the F1 plant inherited what?
one tall allele and one short allele
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.
If a plant has homozygous tall genes what kimd of genes does the plant have?
If a plant is homozygous tall then it would possess two tall genes instead of a short gene. If for the notation you use B to represent the dominant tall gene and b to represent the recessive short gene the plant would carry and "BB" compliment of genes.
When gregor mendel crossed a tall plant with a short plant what did the f1 plant inherit?
They inherited a T (tall) allele from the tall parent, and a t (short) allele from the short parent. This is only if we assume that both parents are homozygous, which the short parent would need to be for the short trait to show. If this is true, then the F1 generation would show the tall trait 4/4 times, and would end up with the genotype Tt 4/4 times.
What offspring would you get if you cross a homozygous tall plant with a homozygous short plant?
Homozygous dominant would be all Capital letters. Homozygous recessive would be all lower case letters. So...in basic color genetics for horses: A homozygous recessive horse would be aaee A homozygous dominant horse would be AAEE
