How was it possible that there were short plants in the f2 generation if there werent any short plants in the f1 generation?

The reason why short plants reappeared in Mendel's F2 generation of pea plants was because their short trait was heterozygous. Both parents carriedÊthat recessive gene, so they passed it on to their offspring.

∙ 12y agoAlthough plants of the F1 generation have the phenotype of tall size, they must be heterozygous in genotype, therefore it is possible for F2 plants to have the phenotype of being short in stature.

∙ 11y agoThe allele for green seeds is recessive; when a yellow-seeded plant and a green-seeded plant were crossed in the parent generation, the genotype of all of the offspring was Yy, so they exhibited yellow seeds, the dominant allele. However, when two plants from the F1 generation (both with a genotype of Yy) were crossed, 25% of the offspring had a genotype of YY, and displayed yellow seeds; 50% of the offspring had a genotype of Yy, and displayed yellow seeds; but 25% of the offspring had a genotype of yy, and displayed green seeds.

What wos the of tall to short plants in the F2 generation of Mendel's experiment?
out of total 1064 plants in f2 generation,787 plants were tall & 277 plants were dwarf.Means 3:1 ratio was obtained.
What was the result of Mendel's experiments in the F2 generation?
There was a 3:1 ratio of tall plants to short plants.
How do you get the f2 generation from the f1 generation?
taken from a science textbook- Scientists today call these parent plants the parental generation, or P generation. The offspring from this cross are the first filial generation or the F1 generation. The word filial comes from filila and flilius, the Latin words for daughter and son. When the plants in the F1 generation were full-grown, Mendel allowed them to self-pollinate. Surprisingly, the plants in the F2 gneration were a mix of tall AND short plants. The shortness trait had reappeared even though none of the F2 parent plants were short. Mendel counted the tall and short plants. About three fourths of the plants were tall, while one fourths were short.

Step 1 of Mendel's garden pea experiments allowing each variety of garden pea to self pollinate for several generations produced which generation?
Mendel found that every fourth plant had white flowers when he allowed the first generation to self-pollinate. Gregor Mendel was a scientist who lived from 1822 to 1884.hyuyt6yt8
Which descides the F2 generation in Mendel's experiment?
three times as many tall plants as short plants
What was the f2 generation in mendels experiment?
There were three times as many tall plants as short plants.

What result did mendel get when he allowed the first-generation plants to self-pollinate?
Gregor Mendel developed the model of heredity that now bears his name by experiments on various charactersitics of pea plants: height (tall vs. Short); seed color (yellow vs. Green); seat coat (smooth vs. wrinkled), etc. The following explanation uses the tall/short trait. The other traits Mendel studied can be substituted for tall and short.Mendel started out with plants that "bred true". That is, when tall plants were self-pollinated (or cross-pollinated with others like them), plants in following generations were all tall; when the short plants were self-pollinated (or cross- pollinated with others like them) the plants in following generations were all short.Mendel found that if true breeding Tall [T] plants are crossed (bred) with true breeding short [t] plants, all the next generation of plants, called F1, are all tall.Next, he showed that self-pollinated F1 plants (or cross- pollinated with other F1 plants) produce an F2 generation with 3/4 of the plants tall and 1/4 short.A. 1/4 of the F2 generation are short plants, which produce only short plants in the F3 generation, if they are self- pollinated (or crossed with other short F2 plants;) these F2 plants breed true.B, 1/4 of the F2 generation (1/3 of the tall plants) are tall plants that produce only tall plants in the F3 generation, if they are self-pollinated; these tall F2 plants breed true.C. 1/2 of the F2 generation (2/3 of the tall plants) are tall plants that produce 1/4 short plants and 3/4 tall plants in the next [F3] generation, if they are self-pollinated. This is the same proportion of tall to short that F1 plants produce.

Will tall plants always have tall offspring?
no. in the second generation it will have a short offspring , but in the first generation it will have tall offspring
