What are the geneotypes of a homozygous and a heterozygous tall pea plant?

The word genotypes is in reference to the alleles an individual receives at fertilization. Lets say that the allele/gene/trait, genotype for the Tall plant is T and dominate and the allele/gene/trait genotype for the short plant is t and recessive. If the genotype is an homozygous allele/gene/trait has two dominate alleles/genes/traits seen as two capital letters ex: dominate tall=TT or if the genotype is homozygous with two recessive alleles/genes/traits it will have two lower case letters ex: short=tt. If the genotype is heterozygous is a Tall plant that means the allele/gene/trait will have one dominate T=Tall and one recessive t=short and it will look like this Tt and with this genotype a Tall plant will be produce "T", even though that plant will still carry an allele/gene/trait for shortness "t". Tips: homozygous [Gk.homo means same and zygous means balance] & heterozygous [Gk.hetero means different and zygous means balance]

∙ 9y agoIf we see a white guinea pig, it's genotype must be "bb". If you look at a pea plant & it is short, its genotype must be "tt". You bump into a two-eyed purple people eater on your way to the mall, its genotype for eyes is "ee", because we all know that in purple people eaters the dominant trait is one eye (EE or Ee).

∙ 12y agoThe genotype is heterzygous, meaning that there are two different alleles. If you want to use letters to represent the tall and short alleles, you could use T for tall (capital letter indicates a dominant allele), and t for short (lowercase letter indicates a recessive allele). So the heterozygous genotype for a tall pea plant could be indicated by Tt.

So homozygous for tall is TT and heterozyous for tall is Tt. Both plants are phenotypically tall.
Wiki User
∙ 12y agoConsidering that tallness is the dominant trait, the genotype of a heterozygous tall pea plant is Tt.

A pea plant with two tall genes is called?
Heterozygous
What is the genotype of a heterozygous tall plant?
DD is homozygous dominant is a genotype which gives tall plant.
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 is the genotype for a homozygous tall plant?
For example, if the tall plant stand for T, the genotypes are: TT tt
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.
What are the genotype a of a homozygous and a heterozygous tall pea plant?
homozygous- TT; heterozygous- Tt :)
A pea plant with two tall genes is called?
Heterozygous
What determines whether an organism is heterozygous or homozygous dominant?
The second allele. If a plant is heterozygous tall, it is Tt. In this case, the dominant trait is tall, T and recessive is short, t. There are two options for it to be dominant, heterozygous (Tt) or homozygous (TT)
What is the genotype of a heterozygous tall plant?
DD is homozygous dominant is a genotype which gives tall plant.
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
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.
What is the genotype for a homozygous tall plant?
For example, if the tall plant stand for T, the genotypes are: TT tt
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.
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 do you get when a heterozygous plant breads with a short plant?
I assume you mean heterozygous dominant tall and short is recessive.T = tall.t = shortTt X tt (called a test cross )1/2 Tt-----------------------heterozygous dominant1/2 tt-----------------homozygous recessive
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)
What is the offspring if you cross two heterozygous Tt tall plants?
You get one homozygous dominant (TT), one homozygous recessive (tt), and two heterozygous (Tt).
