tall plant.
As the given genotype is Tt , it’s a heterozygous condition and in heterozygous condition the dominant trait (T – tall) will express itself. Hence, the phenotype of Tt will be a tall plant.
What is the phenotype of TT?
pure tall
| Genotype Symbol | Genotype Vocab | Phenotype |
|---|---|---|
| TT | homozygous DOMINANT or pure tall | tall |
| Tt | heterozygous or hybrid | tall |
| tt | homozygous RECESSIVE or pure short | short |
What is the phenotype of TT tall or short?
tall
Phenotypes for plant height are tall or short. TT and Tt genotypes both expressed the tall phenotype because the T is dominant to t. Only the tt genotype expressed the short phenotype.
What are the phenotypic and genotypic ratio of TT TT?
Complete answer: When cross takes place between Tt and tt two different types of alleles are form, Tt X tt = Tt, Tt, tt, and tt. The genotypic ratio for this cross is 1:1 and the phenotypic ratio is 1:1, where Tt is heterozygous dominant and tt is heterozygous recessive.
What is TT genotype?
The notation tt means the homozygous condition, wherein the homologous pair contains same alleles of a gene. Alleles are different forms of one gene. In the pea plant, tall and dwarf are the two contrasting traits for stem height. ‘t’ is used for dwarfness, which is recessive.
How do you determine phenotype?
Phenotype refers to an individual’s observable traits, such as height, eye color and blood type. A person’s phenotype is determined by both their genomic makeup (genotype) and environmental factors.
What is a TT plant?
It is a hybrid tall plant as it contains both the alleles but expresses only the tall trait. Since, only the tall trait is expressed in heterozygous (Tt) condition, tallness is dominant over over dwarfness. So, the correct answer is ‘tallness is the dominant trait’
What does a 1 2 1 phenotypic ratio mean?
incomplete dominance
A cross of two F1 hybrids, heterozygous for a single trait that displays incomplete dominance is predicted to give a 1:2:1 ratio among both the genotypes and phenotypes of the offspring.
What is the phenotype and genotype?
The genotype is a set of genes in DNA responsible for unique trait or characteristics while the phenotype is the physical appearance or characteristic of an organism.
What is the phenotype ratio?
A phenotypic ratio is a quantitative relation between phenotypes showing the number of times the frequency of one phenotype correlates with another. When a researcher would like to obtain the gene expression for generations of an organism, they use the phenotypic ratio obtained from a test cross.
What are the gamete possibilities of an organism with the genotype TT?
So in regard to the Tt genotype, the parent organism will produce two different types of gametes, T and t .
Is YY a phenotype?
YY is the homozygous dominant genotype (2 Y alleles). The phenotype of this genotype is yellow seed color. Yy is the heterozygous genotype (one dominant allele, one recessive allele). The phenotype of this genotype is yellow seed color.
How is the phenotype of a pea plant different from its genotype?
An organism’s genotype is its specific combination of alleles for a given gene. So, for example, in the pea plants above, the possible genotypes for the flower-color gene were red-red, red-white, and white-white. The phenotype is the physical manifestation of an organism’s allellic combination (genotype).
What is the phenotype of AA?
The other allele is usually recessive which means it is only expressed if there are no alternate forms of the gene (other alleles) present. Therefore, both the genotypes AA and Aa produce a red feather phenotype.
Which of the following is an example of phenotype?
Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
What are the 3 types of genotypes?
In a nutshell: your genotype is your complete heritable genetic identity; the sum total of genes transmitted from parent to offspring. There are four hemoglobin genotypes (hemoglobin pairs/formations) in humans: AA, AS, SS and AC (uncommon). SS and AC are the abnormal genotypes or the sickle cells.
When a tall pea plant TT is crossed with dwarf plant TT What will be the generation?
In one of the experiments with pea plants, Mendel observed that when a homozygous tall pea plant (TT) is crossed with a homozygous dwarf pea plant (tt), in the first generation, only tall plants appear.
When tall pea plant TT and short pea plant TT were hybridized it produced all tall progeny because tallness is trait?
A cross between a tall plant (TT) and short pea plant (tt) resulted in progeny that were all tall plants because tallness is the dominant trait. Thus, tallness is the dominant trait.
Would these two plants with the genotypes TT and TT have the same phenotype or different one?
Tallness is the dominant trait for plant height; therefore, the genotypes with Tt and TT would have the same phenotype. Correct!
What kind of cross produces a 1 1 phenotypic ratio?
In the monohybrid cross, a testcross of a heterozygous individual resulted in a 1:1 ratio.
What is the phenotype of RR?
A phenotype is a description of what an organism looks like based on its genotype. A person with the Rr genotype for tongue rolling would be able to roll his or her tongue, because he or she has the dominant allele that allows tongue rolling. So “tongue rolling” is his or her phenotype.
