What is Mendels's ratio for dominant to recessive traits?
The Ratio is 3:1
In the F2 generation in Mendel's experiment's the ratio of dominant to recessive traits was?
The ratio of dominant to recessive traits in the F2 generation of Mendel's experiments was 3:1. This is known as the phenotypic ratio for a monohybrid cross, where three individuals display the dominant trait for every one individual displaying the recessive trait.
What is mendels ratio for dominant to recessive traits?
its 3:1
In which generation were recessive traits visible Mendel's experiments?
Recessive traits were visible in the F2 generation of Mendel's experiments, where the offspring of the F1 generation showed a 3:1 ratio of dominant to recessive traits.
In which generation were recessive in all the plants in medel's experiment?
In Mendel's experiments, the recessive traits were observed in the F2 generation. Initially, the traits were not visible in the F1 generation, where only the dominant traits were expressed. However, when the F1 plants were allowed to self-pollinate, the recessive traits reappeared in the F2 generation, typically in a ratio of about 3:1, dominant to recessive.

What was the ratio of dominant of recessive phenotypes in the F2 generation of Mendel's experiments?
The traits were recessive.
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 a first generation plant self pollinates what is the ratio of the dominant to recessive traits in the second generation plants?
1:3
When a first generation plant self pollinates what is the ratio of dominate to recessive traits in the second generation plants?
When a first generation plant self pollinates, the ratio of dominant to recessive traits in the second generation plants is typically 3:1. This is based on Mendel's principle of segregation, which predicts that in a monohybrid cross, three plants will exhibit the dominant trait and one will exhibit the recessive trait.
How will you calculate the phenotype ratio of a cross between dihybrid F1 plants that are heterozygous for 2 dominant traits?
Using a Punnett square, you can calculate the genotype and phenotype of two dihybrid plants. For example, if you have two heterozygous individuals for two dominant traits (we'll pretend the genotype is YyRr), put them into a Punnett square, and you'll get these results: YYRR: 1, YYRr: 2, YYrr: 1 YyRR: 2, YyRr: 4, Yyrr: 2 yyRR: 1, yyRr: 2, yyrr: 1 Phenotypes expressed: Dominant for both traits: 9/16 Dominant for trait 1: 3/16 Dominant for trait 2: 3/16 Recessive for both traits: 1/16 Therefore, the ratio would be 9:3:3:1
In Mendels experiment why did traits show up in F2 generation that were not present in the F1 generation?
All of the F1 generation are heterozygous, therefore 100% exhibit the dominant phenotype. The F2 generation has a ratio of 1 homozygous dominant: 2 heterozygous: 1 homozygous recessive. This results in a phenotypic ratio of 3 dominant: 1 recessive.
In the mendels experiment why did traits show up in the f2 generation that were not present in the f1 generation?
All of the F1 generation are heterozygous, therefore 100% exhibit the dominant phenotype. The F2 generation has a ratio of 1 homozygous dominant: 2 heterozygous: 1 homozygous recessive. This results in a phenotypic ratio of 3 dominant: 1 recessive.
What is the likelihood of a recessive trait being expressed if your offspring is crossed with a homozygous dominant eye shape prove your answer in a cross?
If you cross a homozygous dominant individual (AA) with a heterozygous individual (Aa), the offspring will have a genotype ratio of 100% dominant phenotype (AA or Aa) and 0% recessive phenotype (aa). Therefore, if your offspring has a homozygous dominant trait (AA), the likelihood of expressing a recessive trait (aa) is 0%. The Punnett square for this cross would show all dominant traits, confirming that recessive traits cannot be expressed in this scenario.
