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

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.
How are autosomal traits related to Mendel's observations of heredity?
Gregor Mendel grew hundreds of pea plants. He was curious as to why some of the plants had different traits. Some plants were tall and others were short. Some plants produced green seeds while others produced yellow seeds.Mendel observed that most of the pea plants' traits were similar to its parents. In this observation, Mendel discovered heredity. Heredity is the passing of traits from parents to offspring.Mendel started his experiments with purebred plants, a plant that always produces offspring with the same form of a trait as a parent. Purebred pea plants self-pollinate (pollinate by themselves.) The pistil produces female egg cells. And the stamens produce pollen that contains male sex cells.Next, Mendel cross-pollinated the plants. He took the pollen from a short plant and applied it to a tall plant. He called this generation the parental generation or the P generation. The offspring of this generation was called the first filial generation. The offspring of this first filial generation were all tall. Mendel was curious as to why the tall plant gene over powered the short plant gene. It was because in pea plants tall genes are the dominant allele while short genes are the recessive allele.When the pea plants from the first filial generation were pollinated, three-fourths of the offspring (called the second filial generation) were tall and one-fourth was short. It showed Mendel that recessive alleles can reappear in the next generation of plants.Some Key AbbreviationsT = dominant allelet = recessive alleleTT = (purebred) a plant that inherited two dominant allelesTt = (hybrid) a plant that inherited one dominant allele and one recessive allelett = (purebred) a plant that inherited two recessive alleles
Gregor Mendel's studies?
Gregor Mendel studied genetics by observing generation of pea plants. By altering a single factor there were no changes first generation, but by second generation the variables were exposed.
What describes F2 generation in Mendel's experiments?
Three times as many shorts plants as tall plants.
What was the result of Mendel's experiments in the F2 generation?
There was a 3:1 ratio of tall plants to short plants.
When Gregor Mendel crossed purebred short plants with purebred tall plants all of the offspring were?
tall.
When Mendel crossed purebred short plants with purebred tall plants all of the offspring were?
I think not as tall is the dominant allele here.T = tallt = shortTT X ttall would beTt======and tall.
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 !
What pollinations did mendel use to produce purebred plants?
Cross Pollination
What were gregor Mendel's experiment's?
i believe his results were that after cross pollinating to non-purebred pea plants, the offspring were all tall like the female,and when he crossed the other two, he received three tall pea plants and one short

What was the main experiments Gregor Mendel carried out?
In mendels first experiments, he crossed pea plants to study seven different characteristics. For example he crossed plants that had purple flowers with plants that had whit flowers, the offsprings from such a cross are called first- generation plants. All of his first generation plants had purple flowers. One trait was always present in the first generation , and the other trait seemed to disappear. Mendel chose to call the trait that appeared the dominant trait. Because the other trait seemed to fade into the background, Mendel called it recessive trait.
What was the result of the first generation of pea plants that mendel bred?
P generation.
What was the result of the first gemeration of pea plants that Mendel bred?
The first generation of of pea plants that Mendel bred were tall.

Altered characteristics of organisms from one generation of plants to another?
Gregor mendel
How did Mendel's use of purebred plants for example purebred white and purebred purple-flowered peas-contribute his understanding of inheritance?
Gregor Mendel took two different colored pea plants: one had traits for white plants and the other had traits for a red plant. When Mendel cross bred the two plants, a plant with traits for a pink plant grew. This is how Mendel contributed to the understanding of inherited traits.
