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 are the genotype a of the parents?
genotype of the parents - parents will be heterozygous dominant. e.g. take the example of Mendel's pea cross. if parent is heterozygous dominant then the genotype will be Tt and Tt now if you will do a cross then the result you will get is this - Tt X Tt result - TT, Tt, Tt, tt it gives a 3 : 1 ratio i.e. three tall and one dwarf.

In pea plants the gene for tallness (T) is dominant over the gene for shortness (t). A homozygous dominant pea plant is crossed with a heterozygous pea plant and 200 seeds are produced. Approximately?
When a homozygous dominant pea plant (TT) is crossed with a heterozygous pea plant (Tt), the possible genotypes of the offspring are TT and Tt. This results in a 1:1 ratio of tall (TT and Tt) to short (tt) plants. Therefore, out of 200 seeds produced, approximately 200 seeds will be tall plants (100 TT and 100 Tt) and 0 seeds will be short (tt).
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 are the phenotypes of two dominant alleles?
If two alleles are dominant, the phenotypes will reflect the dominant traits associated with each allele. Both alleles will be expressed in the phenotype, resulting in a phenotype that shows the dominant characteristics of both alleles.
What is the phenotype for Tt x Tt?
Tt X Tt Statistically, 1 TT Homozygous dominant, expresses T. 2 Tt Heterozygous dominant, expresses T. 1 tt Homozygous recessive, expresses t.
What is true of the allele pair of someone with a genotype TT?
The allele pair of someone with a genotype TT is homozygous dominant.
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 two alleles could produce a trait controlled by a dominant allele?
Tt or TT
Which two combinations of allels could produce a trait controlled by a dominant allele?
with TT or Tt
Does a pea plant with the genotype TT has the same phenotype as a pea plant with genotype tt?
No because T resembles a dominant trait and t resembles a recessive trait. If it is TT, that means there are 2 dominant traits, and for TT there are 2 recessive traits.
What are the genotype a of the parents?
genotype of the parents - parents will be heterozygous dominant. e.g. take the example of Mendel's pea cross. if parent is heterozygous dominant then the genotype will be Tt and Tt now if you will do a cross then the result you will get is this - Tt X Tt result - TT, Tt, Tt, tt it gives a 3 : 1 ratio i.e. three tall and one dwarf.

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.
What is true of someone with a genotype TT?
it is homozygous dominant
What is true of someone with genotype TT?
it is homozygous dominant
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).
What are the genotypes of a dominant tall pea plant to short pea plants?
Really, there is no set letter for any allele. It is common, however, to use the first letter of the dominant allele. Since tall height is dominant over short height in pea plants, then the allele for short would be the t (a lowercase t).
