No, "tt" is not commonly used as an abbreviation for "estimated." The abbreviation for "estimated" is typically "est." or "est." depending on the context. "TT" could stand for various other terms, such as "Table Tennis" or "teletype," but it does not relate to "estimated."
What else can I help you with?
Tall is dominate over short The genotype of a short plant is what?
Tall = T short = t Tall plants genotype would either be TT or Tt, and short plants genotype would be tt.
In pea plants the allele for tallness is dominant. What are the possible genotypes of a tall pea plant?
the tall plant must be heterozygous
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 are the genotypes of the short plants in the P1 and F2 generation?
P1: tt F2: tt
When two pea plants with TT genotypes are crossed-bred how many short tt plants will there be in the new generation?
In the offspring generation from crossing two pea plants with TT genotypes, all the offspring will have the genotype Tt. However, all of these offspring will be tall since the tall trait is dominant (T) over the short trait (t). Therefore, there will be no short tt plants in the new generation.
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).
What does TT mean when it appears on a dinghy?
TT is short for "Tender To". so if a yacht named Rosmarie has a dinghy tender, the dinghy could be named "TT Rosmarie" .
What letters can be used to model Mendels cross of true-breeding tall plants what true-breeding short plants in a Punnett square?
TT for the homozygous tall parent, tt for the homozygous short parent and Tt for the heterozygous offspring.
In the P generation a tall plant is crossed with a short plant The probability that an F2 plant will be tall is?
75% there will be TT, Tt, Tt, and tt. tt is going to be short. This means that 3/4 will be tall. 3/4 is 75%
What is the symbol for the genotype of true breeding tall plants short is Dominant?
if we assume tall plant <T> & short plant as< t> genotype of tall plant ; TT genotype of short plant ; tt
What letters can be used to model Mendel's cross of true-breeding tall plants with true-breeding short plants in a Punnett square?
Generally speaking, the letters used to represent cross breeding in Punnett squares indicate the characteristic being bred for. In this case, T would represent the tall plants, and S would represent the short plants. Cross-bred plants would most likely be represented by TS.
T is genetic trait for tallness and its allele t is recessive for tallness and their are four children with alleles TT tT Tt tt how many will be tall?
OK first, you don't say tT. The dominant allele is always put first. So this would actually be TT Tt Tt and tt. The only way a recessive trait will show is if the dominant trait isn't present. Therefore 3 will be tall and one will be short. BTW: TT isn't an example of an allele. It's actually the genotype. T is an example of an allele. Tallness is a genetic trait, but T is not. A genetic trait is simply a title that includes whatever phenotype may become apparent. A phenotype is the trait that shows up. If a person's genotype is TT or Tt, their phenotype will be tall. If a person's genotype is tt, then their phenotype will be short.
