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.

∙ 12y agosome of the F2 plants produced gametes that carried the allele for shortness.
If you look at the Punnet Square you'll see this because:
TT x tt =
Tt | Tt
Tt | Tt
Because the tall trait is a dominant trait, a plant must have both of the recessive traits (ie: tt) to be a short plant). When two of the F1 are mixed, then you have a 25% chance of having a short plant:
Tt x Tt =
TT | Tt
Tt | tt

The trait that disappeared in the f1 generation?
reappears in some plants in the F2 generation
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 result did Mendel get in F1 generation when he crossed purebred tall plants with purebred short plants?
When Mendel crossed two hybrid plants for stem height, three fourths of the F1 plants always had tall stems. One fourth of the plants had short stems.Mendel always got a dazzling and great result. It was always 3/4 that were tall and 1/4 that were short
Why did Mendel use true breeding plants in P generation?
BEcause cross pollinating

3/4th of them do

When plants that are true breeding for different traits of a characteristic are crossed the offspring are called?
first-generation plants
When parent plants are crossed how do scientists refer to the first generation of offspring?
F1

What is a trait that reappears in the second after disappearing in the first generation?
A recessive trait reappears in the 2nd generation. The classic example of this would be Gregor Mendel's pea plant cross. He took 2 pea plants, one short and one tall, cut out some of their reproductive parts so they couldn't self pollinate, and crossed their pollen. However, instead of getting a medium sized plant, he got 4 tall plants. This generation is the first, or F1, generation. Where did the short trait go? Did it simply disappear? Or was it being masked? To find out, he let the F1 generation self-pollinate. Surprisingly, there were 3 tall and 1 short plants in the F2 generation. Although the short trait was recessive, it reappeared in the second generation.
What generation did Mendel get when he crossed the plants that produced the F1 generation?
100% percent of the plants expressed the dominate trait ........................................................................................ what do u get when u mix purple with purple you get 100% purple :) simple peace of cake !
