What is TT in genetics notation?
The notation Tt means the heterozygous condition , wherein the homologous pair contains different alleles of a gene. ... ‘Tt’ refers to the heterozygous condition with a dominant and a recessive allele and tallness being the dominant trait, it is expressed in the phenotype.
Why do TT and TT genotypes have the same phenotype?
Tallness is the recessive trait for plant height ; therefore, the genotypes with Tt and TT would have the same phenotype. ... Tallness is a recessive trait in pea plants. C. Tallness is the dominant trait for plant height; therefore, the genotypes with Tt and TT would have the same phenotype.
What is the difference between heterozygous and homozygous inheritance?
Heterozygous refers to having inherited different forms of a particular gene from each parent. A heterozygous genotype stands in contrast to a homozygous genotype , where an individual inherits identical forms of a particular gene from each parent.
Is TT a hybrid?
The petrol-powered Audi TT – first introduced in 1998 – will be replaced with an electric sports car in a few years’ time, company chairman Bram Schot has said. ... As such, both plug-in hybrid and fully-electric TTs are under consideration.
Is TT a gene or allele?
| Genotype Definition Example | Homozygous Two of the same allele TT or tt | Heterozygous One dominant allele and one recessive allele Tt |

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 .
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 |

Is FF heterozygous or homozygous?
| 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 is the phenotypic ratio of a cross between TT and 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 an example of heterozygous?
If the two versions are different, you have a heterozygous genotype for that gene. For example, being heterozygous for hair color could mean you have one allele for red hair and one allele for brown hair . The relationship between the two alleles affects which traits are expressed.
What is another name for heterozygous?
In this page you can discover 11 synonyms, antonyms, idiomatic expressions, and related words for heterozygous, like: homozygous , genotype, allele, recessive, MTHFR, C282Y, rb1, heterozygote, premutation, wild-type and homozygote.
How do you determine if a person is homozygous or heterozygous?
If an organism has identical genes on both chromosomes , it is said to be homozygous. If the organism has two different alleles of the gene it is said to be heterozygous.
What will replace the TT?
Audi has confirmed that the next-generation TT will be an all-electric sports car. The news comes from Audi chairman Bram Schot, who told the firm’s annual general meeting that the current TT would be replaced with an electric variant “in a few years”.
What is replacing the Audi TT?
The Audi TT Is Getting Replaced by an “Emotive” Electric Car . The new model will sit in the same price range as the current TT. The Audi TT will be replaced in a few years by a new, fully electric model that might not be a sports car at all. Audi says the new EV will be “emotive” and priced like the current TT.
Is TT a genotype or phenotype?
Genotypes for plant height are TT, Tt, tt. Genotypes can be heterozygous or homozygous. Phenotypes for plant height are tall or short. TT and Tt genotypes both expressed the tall phenotype because the T is dominant to t.
