In genetics, "tt" represents a homozygous recessive genotype for a specific trait, where both alleles for that trait are recessive. This means that the individual will express the recessive phenotype associated with that trait, as there are no dominant alleles present to mask the effect. For example, if "t" represents a trait for short height in plants, a plant with the genotype "tt" would be short.
What else can I help you with?
What is Having two unlike genes for the same trait?
When two alleles differ from each other, such as Tt, it is called heterozygous, hetero meaning different. When alleles are the same (TT) it is called homozygous, homo meaning same.
What is the difference between the genotypes between TT and Tt?
The genotypes TT and Tt represent different combinations of alleles for a particular gene. TT is homozygous dominant, meaning it has two identical dominant alleles, while Tt is heterozygous, containing one dominant allele (T) and one recessive allele (t). This difference can affect the expression of traits, with TT typically exhibiting the dominant phenotype and Tt also showing the dominant phenotype, but potentially carrying the recessive trait.
What combinations of alleles could produce a trait controlled by a recessive alleles?
recessive + recessive or tt
What are organisms that have two different alleles?
When you have two identical alleles you are said to be homozygous for that particular trait. If the trait is dominant, then you are homozygous dominant. If the trait is recessive, then you are homozygous recessive.
What genotype is homozygous?
A homozygous genotype refers to having two identical alleles for a particular gene. It can be either homozygous dominant (two dominant alleles, such as AA) or homozygous recessive (two recessive alleles, such as aa).
What is Having two unlike genes for the same trait?
When two alleles differ from each other, such as Tt, it is called heterozygous, hetero meaning different. When alleles are the same (TT) it is called homozygous, homo meaning same.
What is the difference between the genotypes between TT and Tt?
The genotypes TT and Tt represent different combinations of alleles for a particular gene. TT is homozygous dominant, meaning it has two identical dominant alleles, while Tt is heterozygous, containing one dominant allele (T) and one recessive allele (t). This difference can affect the expression of traits, with TT typically exhibiting the dominant phenotype and Tt also showing the dominant phenotype, but potentially carrying the recessive trait.
What is TT Tt tt?
These are letters assigned to alleles or variations in genes. TT means that there are two dominate alleles. Tt means that there is one dominate and one recessive and tt means that both are recessive.
How many combinations of alleles could there be in zygotes produced by crossing the following parents TT x Tt?
When crossing the parents TT (homozygous dominant) and Tt (heterozygous), the possible combinations of alleles in the zygotes can be determined. The TT parent can only contribute a T allele, while the Tt parent can contribute either a T or a t allele. Therefore, the possible combinations of alleles in the zygotes are TT and Tt, resulting in two distinct combinations.
What has 2 genes or alleles like TT or tt?
An organism with two genes or alleles, such as TT or tt, is said to be homozygous for a particular trait. In this case, TT represents a homozygous dominant genotype, while tt represents a homozygous recessive genotype. These genotypes can influence the organism's phenotype, or observable characteristics, depending on the dominance of the alleles involved. For example, if T is dominant over t, the phenotype of TT and Tt would be the same, while tt would have a different phenotype.
What two alleles could produce a trait controlled by a dominant allele?
Tt or TT
What combinations of alleles could produce a trait controlled by a recessive alleles?
recessive + recessive or tt
What are organisms that have two different alleles?
When you have two identical alleles you are said to be homozygous for that particular trait. If the trait is dominant, then you are homozygous dominant. If the trait is recessive, then you are homozygous recessive.
What genotype is homozygous?
A homozygous genotype refers to having two identical alleles for a particular gene. It can be either homozygous dominant (two dominant alleles, such as AA) or homozygous recessive (two recessive alleles, such as aa).
A plant with the genotype TT is called?
Genotype TT is called a homozygous genotype. The TT indicates identical alleles, and the capital letters represent their dominant trait.
What type of alleles are presented in a homozygous genotype?
homozygous(different gene)-Rr heterozygous(same gene)-RR,rr
Genetics Tt and TT are examples of?
Genetics Tt and TT are examples of genotypes, which represent the combination of alleles (T and t) that an organism carries for a particular trait. In this case, T represents the dominant allele and t represents the recessive allele. TT is a homozygous dominant genotype, while Tt is a heterozygous genotype.
