The Ratio is 3:1
The ratio of dominant traits to recessive traits in a given characteristic depends on the specific genetic makeup of the individual. In general, dominant traits are more commonly expressed than recessive traits. However, the ratio can vary depending on the specific traits being considered and the inheritance patterns involved.
In second generation plants, the typical ratio of dominant traits to recessive traits, based on Mendelian genetics, is 3:1. This ratio occurs when two heterozygous parents (both carrying one dominant and one recessive allele) are crossed. The dominant trait appears in approximately 75% of the offspring, while the recessive trait appears in about 25%.
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.

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.

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 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.
The traits were recessive.
In a two-factor cross where both parents are heterozygous for two traits (e.g., AaBb x AaBb), you would expect a phenotypic ratio of 9:3:3:1 in the offspring. This ratio represents the combinations of the dominant and recessive traits for both factors. The 9 represents the offspring with both dominant traits, while the 3s represent the combinations with one dominant and one recessive trait, and the 1 represents the offspring with both recessive traits.
In Mendel's experiments, recessive traits were hidden in the F1 generation, which consisted of the offspring resulting from the cross of two purebred parent plants with contrasting traits. These F1 plants exhibited only the dominant traits, while the recessive traits were not expressed. However, when the F1 plants were self-pollinated to produce the F2 generation, the recessive traits reappeared in a predictable ratio alongside the dominant traits.
1:3
In Mendel's experiments, recessive traits were hidden in the F1 generation. When he crossed pure-breeding plants with contrasting traits, all offspring in the F1 generation exhibited the dominant trait. It was only in the F2 generation, produced by self-pollinating the F1 plants, that the recessive traits reappeared in a 3:1 ratio alongside the dominant traits.
To achieve a phenotype ratio of 9:3:3:1 in offspring, you would need to perform a dihybrid cross between two heterozygous individuals (AaBb x AaBb) for two traits that assort independently. Each trait should have two alleles, with dominant alleles producing the dominant phenotypes. This cross results in the classic Mendelian ratio where 9 offspring display both dominant traits, 3 show the dominant trait for the first and recessive for the second, another 3 show recessive for the first and dominant for the second, and 1 exhibits both recessive traits.
