To determine the ratio of tall plants to short plants, you need to count the number of each type. For example, if there are 10 tall plants and 5 short plants, the ratio would be 10:5, which can be simplified to 2:1. If you have different counts, simply use the same method to find the ratio.
In Mendel's experiments with pea plants, the ratio of tall to short plants in the F1 generation was 100% tall, as tall (dominant) traits masked the short (recessive) traits. However, in the F2 generation, after self-pollinating the F1 plants, the ratio of tall to short plants was approximately 3:1, with three tall plants for every one short plant.
In Mendel's experiments, the ratio of tall to short plants in the F2 generation is typically 3:1. This is known as the Mendelian ratio, which is a result of the segregation of alleles during gamete formation and fertilization.
The 3:1 ratio of tall to short pea plants in the F2 generation supports Gregor Mendel's Law of Segregation. This law states that alleles for a trait segregate independently during gamete formation, leading to the predictable inheritance patterns observed in offspring. In this case, the dominant allele for tall plants (T) segregates from the recessive allele for short plants (t), resulting in a majority of tall plants when two heterozygous parents (Tt) are crossed.
When Mendel crossed purebred tall tea plants with purebred short tea plants, all the offspring in the first generation (F1) exhibited the tall phenotype. This outcome demonstrated the concept of dominance, where the tall trait masked the short trait. When Mendel allowed these F1 plants to self-pollinate, the second generation (F2) revealed a 3:1 ratio of tall to short plants, indicating that the short trait was still present as a recessive trait. This experiment laid the foundation for Mendel's laws of inheritance.
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.

3 dominant to 1 recessive
In Mendel's experiment, the ratio of tall to short plants in the F2 generation was approximately 3:1. This ratio is explained by Mendel's law of segregation, which states that alleles separate randomly during gamete formation, resulting in different combinations in offspring.
