i think he used cross breeding(I think) in the F1 generation, then used the results to self pollinate. dont quote me i am not sure, just what i would think.

3:1 was the ratio of plants expressing contrasting traits that Gregor Mendel calculated in his F2 generation of garden peas.

he found out that it was a 3:1 ratio which is 0.3333333...... bye me

Mendel found a fixed pattern of inheritance in the ratio of 3:1 in the contrasting characters from F1 generation to F2.

Mendel used the mathematics in his experiments. He found the ratio of the pea plants who were tall to who were short if every generation and gave the law of inheritance.

For each of the seven characters Medel studied,he found the same 3:1 ratio of plants expressing the contrasting traits in the f2 generation.

Gregor Mendel was able to determine traits by the ratio in which they appeared. For instance, he determined that a recessive trait will show up 25 percent of the time if one parent has it.

Mendel worked with sweet peas. Not all organisms have such straight forward genetics.

Gregor Mendel was a monk and a teacher. He discovered genetics. He used pea plants to represent the 1 to 2 to 1 ratio. He mixed green and yellow peas seeds, and found out (after many tries) that the characteristics of two different peas would grow a new pea. For example: he put a wrinkly yellow pea with a smooth green pea and they grew into a wrinkly green pea.

Mendel observed phenotypes for seven contrasting characters segregating in to three is to one ratio mathematically and thus he propounded the principle dominance and recessive characters

For monohybrid cross the genotype ratio in f2 generation would be 1:2:1 and phenotype ratio would be 3: 1

Mendels' f2 generation produce a 3:1 ratio of tall plants. By crossing true tall with true short , homologous chromosomes, he wound up with three types of plants, true tall, true short, and tall with a short allele.

No. It can be but need not be. For example, you might calculate the ratio of today's temperature in Celsius and in Fahrenheit and calculate the ratio. That is not a rate.

Around 1857, Gregor Mendel began breeding green peas to study inheritance. Although heredity was still unknown at the time, Mendel was curious about the subject. Mendel worked with green peas because they were simple to test, produced large numbers of offspring, and had different variety of traits. Mendel discovered that when he bred two true-breeding peas: one purple and one white (a purple flower's offspring will always turn out purple) produced offspring of purple flowers (why was it only purple and not white?) because the trait for a purple color for peas is more dominant. Then he decides to breed those new purple flowers. Mendel found a 3 to 1 ratio of purple and white flowers. This led to two laws from Mendel: the law of segregation and the law of independent assortment.He studied the effects genetics had on the colors of the flowers of a plant.
