What are the genotypes of the short plants in P1 and F2 Generations?
Because the shot gene in the pea plant is a recessive trait, there is only one possible genotype for it: tt
In the P generation a tall plant was crossed with a short plant No F1 plants were short Short plants reappeared in the F2 generation because?
A cross between members of the F1 generation (Tt x Tt), results in the genotypic ratio of 1TT:2Tt:1tt genotypes in the F2 generation. Because the tall allele is dominant, the phenotypic ratio would be 3 tall:1 short in the F2 generation.
What was the ratio of tall to short plants in the F2 generation mendel experiments?
3.1
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.
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.
What are the genotypes of the short plants in the P1 and F2 generation?
P1: tt F2: tt
In the p generation a tall plant was crossed with a short plant. Short plants reappeared in the f2 generation because?
A cross between members of the F1 generation (Tt x Tt), results in the genotypic ratio of 1TT:2Tt:1tt genotypes in the F2 generation. Because the tall allele is dominant, the phenotypic ratio would be 3 tall:1 short in the F2 generation.

What are the genotypes and phenotypes of a cross between a true breeding tall and a true breeding short pea plant?
The results of the first generation were 3 tall plants and 1 short plant, indicating that some activity was making the tall plants more likely, but not exclusively so.
In the P generation a tall plant was crossed with a short plant No F1 plants were short Short plants reappeared in the F2 generation because?
A cross between members of the F1 generation (Tt x Tt), results in the genotypic ratio of 1TT:2Tt:1tt genotypes in the F2 generation. Because the tall allele is dominant, the phenotypic ratio would be 3 tall:1 short in the F2 generation.
What was the ratio of tall to short plants in the F2 generation mendel experiments?

What was the ratio of tall to short plants in the F generation of Mendel's experiments?
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 experiment why were f2 plants34 tall and 14short?
In Mendel's experiment with pea plants, he observed a phenotypic ratio of approximately 3:1 in the F2 generation when crossing two heterozygous tall plants (Tt). The tall phenotype (T) is dominant, while the short phenotype (t) is recessive. From the genotypes of the offspring, 34 tall plants and 14 short plants indicate that 3 out of 4 plants express the dominant trait (tall) and 1 out of 4 express the recessive trait (short), consistent with Mendel's law of segregation.
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.
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.
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.
