In a typical monohybrid cross involving two heterozygous parents (Tt x Tt), the F2 generation would have a genotype ratio of 1:2:1 for TT, Tt, and tt respectively. This means that 25% of the F2 generation would have the genotype tt. Thus, the percentage of the F2 generation with the genotype tt is 25%.
What else can I help you with?
When the offspring were allowed to self pollinate one out of four produced green peas. What was the genotype of the pea plants that produced green peas in the F2 generation?
In the F2 generation, the offspring that produced green peas likely had the genotype "tt," where "t" represents the allele for green peas and "T" represents the allele for yellow peas. Since one out of four offspring produced green peas, this follows a typical Mendelian ratio of 1:2:1 for a monohybrid cross. The parental generation would have been heterozygous (Tt), allowing for the segregation of alleles.
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%
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.
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.
What are the genotypes of the short plants in P1 and F2 Generations?
Because the shot gene in the pea plant is a recessive trait, there is only one possible genotype for it: tt
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)
What are the genotypes of the short plants in the P1 and F2 generation?
P1: tt F2: tt
In the p generation a tall plant was crossed with a short plant. Short plants reappeared in the f2 generation because?
A cross between members of the F1 generation (Tt x Tt), results in the genotypic ratio of 1TT:2Tt:1tt genotypes in the F2 generation. Because the tall allele is dominant, the phenotypic ratio would be 3 tall:1 short in the F2 generation.
When the offspring were allowed to self pollinate one out of four produced green peas. What was the genotype of the pea plants that produced green peas in the F2 generation?
In the F2 generation, the offspring that produced green peas likely had the genotype "tt," where "t" represents the allele for green peas and "T" represents the allele for yellow peas. Since one out of four offspring produced green peas, this follows a typical Mendelian ratio of 1:2:1 for a monohybrid cross. The parental generation would have been heterozygous (Tt), allowing for the segregation of alleles.
In the P generation a tall plant was crossed with a short plant No F1 plants were short Short plants reappeared in the F2 generation because?
A cross between members of the F1 generation (Tt x Tt), results in the genotypic ratio of 1TT:2Tt:1tt genotypes in the F2 generation. Because the tall allele is dominant, the phenotypic ratio would be 3 tall:1 short in the F2 generation.
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%
Why was 3 1 the ratio in Mendels F2 generation?
In Mendel's F2 generation, the 3:1 ratio observed for dominant to recessive traits arises from the segregation of alleles during gamete formation. When he crossed heterozygous parents (Tt), the resulting offspring can inherit combinations of alleles that produce three dominant phenotype offspring (TT or Tt) and one recessive phenotype offspring (tt). This reflects the principles of Mendelian inheritance, specifically the law of segregation, where each parent contributes one allele for a trait, leading to the 3:1 phenotypic ratio in the F2 generation.
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.?

In contrast, phenotype refers to the observable traits or characteristics that result from the interaction of the genotype with the environment.
What genotype is a tall pea plant?
A tall looking pea plant can have a genotype of Tt or TT.
The combination Tt represents what genotype?
A heterozygous genotype
