What would the phenotype of TT be?
The phenotype of a plant with the genotype Tt would be tall . ... Tallness and dwarfness (stem height) are one of the seven contrasting pairs of traits in pea plants studied by Mendel.
What is the genotype 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 does TT allele mean?
The notation Tt means the heterozygous condition , wherein the homologous pair contains different alleles of a gene. One homologous chromosome possesses the dominant allele and the other chromosome possesses the recessive allele present for a gene.
Is TT a phenotype?
The offspring with the genotypes TT and Tt will have a phenotype of tall ; the offspring with the genotype of tt will have a phenotype of short. If the two alleles are the same (TT or tt), the genotype is considered purebred. If the two alleles are different (Tt), the genotype is considered hybrid.
Is TT tall or short?
| 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 are the 3 laws of Mendel?
Answer: Mendel proposed the law of inheritance of traits from the first generation to the next generation. Law of inheritance is made up of three laws: Law of segregation, law of independent assortment and law of dominance .
What is the difference between genotype and phenotype?
The sum of an organism’s observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism’s parents, the phenotype is not . Whilst a phenotype is influenced the genotype, genotype does not equal phenotype.
Which allele is always written first?
The alleles are represented by letters. The letter chosen is usually the first letter of the trait. Two letters are used represent a trait.
What does genotype TT mean?
When an organism has two of the same alleles for a specific gene, it is homozygous (homo means “same”) for that gene. An organism can be either homozygous dominant (TT) or homozygous recessive (tt). If an organism has two different alleles (Tt) for a certain gene, it is known as heterozygous (hetero means different).
Is TT * TT a test cross?
Testcross is a cross of any genotype exhibiting a dominant phenotype with a recessive homozygote to decide whether it is a heterozygous or homozygous dominant, the genotype of a dominant parent. The dominant phenotype is seen by being a hybrid Tt, and tt is the recessive parent. It is said as a test cross.
What’s an example of phenotype?
The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. ... Examples of phenotypes include height, wing length, and hair color .
Is FF homozygous or heterozygous?
| Genotype Phenotype | F F Homozygous dominant No cystic fibrosis (Normal) | F f Heterozygous Carrier (has no symptoms but carries the recessive allele) | f f Homozygous recessive Cystic fibrosis (has symptoms) |

What are the 3 types of genotypes?
There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous .
Are alleles DNA?
Except in some viruses, genes are made up of DNA, a complex molecule that codes genetic information for the transmission of inherited traits. Alleles are also genetic sequences, and they too code for the transmission of traits. ... The short answer is that an allele is a variant form of a gene .
