What is ratio for PHenotypic ration TT Tt TT Tt?
The phenotypic ratio for the given genotypes (TT, Tt, TT, Tt) can be determined by identifying the traits represented by these genotypes. In this case, both TT and Tt result in the dominant phenotype, while there are no recessive phenotypes present. Thus, the phenotypic ratio is 4:0, indicating that all offspring display the dominant trait.
What is the ratio if TT and tt are crossed?
When a true-breeding tall plant (TT) is crossed with a true-breeding short plant (tt), all the offspring in the first generation (F1) will be heterozygous (Tt) and exhibit the tall phenotype, as tall (T) is dominant over short (t). Therefore, the phenotypic ratio of the offspring will be 100% tall. If these F1 plants are then crossed with each other (Tt x Tt), the resulting phenotypic ratio in the second generation (F2) will be 3 tall (TT or Tt) to 1 short (tt).
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 will be the ratio produced if Tt is crossed with tt?
The ratio produced would be 1:1 for heterozygous (Tt) offspring to homozygous recessive (tt) offspring. This is because the parent with genotype Tt will pass on one dominant allele (T) and one recessive allele (t) to its offspring, resulting in a 50% chance of either genotype in the offspring.
What is the ratio produced if Tt is crossed with tt?
The ratio produced if Tt is crossed with tt is 1:1 for the genotype and 1:1 for the phenotype. This is because all the offspring will inherit a recessive allele from the tt parent, resulting in all of them having the same genotype and phenotype.
In a cross between a pea plant with the genotype TT and a pea plant with the genotype Tt percent of the offspring will be Tt.?
false
What is an organism allele pairs like TT or tt or Tt is it genotype or phenotype?
An organism's allele pairs, such as TT, tt, or Tt, represent its genotype. The genotype refers to the specific genetic makeup of an organism, including the alleles it carries. In contrast, phenotype refers to the observable traits or characteristics that result from the interaction of the genotype with the environment.
Does a Tt plant have the same genotype as a TT plant?
Nope! TT is the dominant phenotype (what ever it may be) and tt is the recessive phenotype (what ever that may be).So say T is the allele for Tall plants, t is the allele for short plants. TT would be show the tall phenotype while tt would show the short phenotype. If the genotype was Tt, the phenotype would be tall as well because the T is dominant and masks the phenotype of t (short plants).
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 genotype is a tall pea plant?
A tall looking pea plant can have a genotype of Tt or TT.
What are organisms with the genotype tt is also know as?
two capital or two lowercase letters in the GENOTYPE (ex: TT or tt) it's also called HOMOZYGOUS.
Pure breeding long stem and pure breeding short stem pee plants are crossed According to Mendel's laws of heridity what will the f2 generation be?
Allele for tall stem (dominant)- T Allele for short stem (recessive)- t The F1 generation would all be tall-stemmed plants with the genotype Tt (heterozygous). The F2 generation would consist of: 25% Tall plants with the genotype TT (homozygous dominant) 50% Tall plants with the genotype Tt (heterozygous) 25% Short plants with the genotype tt (homozygous recessive)
