Asuming that the F1 generation is heterozygous for a single trait and that the F2 cross is of 2 F1 offspring. Ex. Aa X Aa the phenotypic ratio is 3:1 dominant to recessive. The genotypic ratio is 1:2:1 AA:Aa:aa.

What is the phenotypic ratio of PpRr X Pprr?
To determine the phenotypic ratio of the cross PpRr (heterozygous for both traits) and Pprr (heterozygous for the first trait and homozygous recessive for the second), we can set up a Punnett square. The offspring will display four phenotypes based on dominant and recessive traits for both characteristics. The resulting ratio is 3:1 for the first trait (P vs. p) and 1:1 for the second trait (R vs. r), leading to a combined phenotypic ratio of 3:1:1:1 (3 dominant for the first trait and 1 recessive for both traits).
When flies having a gray body and normal wings were crossed with flies having a black body and vestigial wings the F2 generation showed a phenotypic ratio of 3 1 and not 9 3 3 1?
Your answer is A
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.
What is the ratio of Two triangles that are similar and have a ratio of similarity of 310 what is the ratio of their areas?
If the ratio of similarity is 310, then the ratio of their area is 96100.
What is eqivalent ratio?
an eqivalent ratio is an ratio that is equal or you can simplfiy it
What is the cell structure of a red algae?
what is phenotypic ratio and gnotypic ratio
What is phenotypic ratio?
It is the ratio of physical characteristics of parents and the potential offspring traits. It is the ratio of physical characteristics of parents and the potential offspring traits.
What will be the phenotype ratio of the offspring?
9:3:3:1 is the phenotypic ratio of the offspring.
What is the phenotypic ratio of the offspring when a tall man marries a short woman?
The phenotypic ratio of the offspring when a tall man marries a short woman is 3:1 (tall/short). The phenotypic ratio is figured by using the punnet square with the dominant allele for tall and the recessive allele for the short gene.
What is the phenotypic ratio rrgg x RrGg?
3:1
If both parents were Dd then what would the phenotypic ratio be?
If both parents were Dd, they would both be heterozygous for a particular trait. The phenotypic ratio of their offspring would likely be 1 dominant : 2 heterozygous : 1 recessive. This is because the dominant allele masks the recessive allele, resulting in a 3:1 ratio.
What is the actual ratio of the phenotypic characteristics red 93 white 36?
The ratio of red to white phenotypic characteristics is approximately 93:36, which simplifies to 31:12 when divided by their greatest common factor of 3.
Genetic condition that might generate a 2 to1 phenotypic ratio?
Lethality
What is the phenotype of an individual heterozygous of both?
The phenotypic ratio would be 3 to 1
What is the phenotype of an individual heterozygous of both traits?
The phenotypic ratio would be 3 to 1
How can one determine the phenotypic ratio in a genetic cross?
To determine the phenotypic ratio in a genetic cross, you can use Punnett squares to predict the possible outcomes based on the genotypes of the parents. By analyzing the combinations of alleles passed down from each parent, you can calculate the ratio of different observable traits or characteristics in the offspring.
Why does the expected genotypic ratio often differ from the expected phenotypic ratio from monohybrid cross?
Because in heterozygotes, both alleles are transcribed and translated.
