75%
there will be TT, Tt, Tt, and tt. tt is going to be short. This means that 3/4 will be tall. 3/4 is 75%

What is the trait that always appears in the second 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.
How did mendel make th F1 generation for his expiriments?
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.
Why are all the first generation plants tall even though one parent plant is short?
Hhh
When gregor mendel crossed a tall plant with a short plant the f1 plants inherited which allele copies?
one allele from each parentThe F1 generation inherited one dominant (tall) allele from the tall parent and a recessive (short) allele from the short parent. The F1 generation were heterozygous and tall.
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 certain plants tall is dominant to short If a heterozygous plant is crossed with a homozygous tall plant what is the probability that the offspring will be short?
0 (there is no chance it will be short since tall is dominant over short). Hope this helps! - Biology Student
What was the result when gregor mendel crossed a tall plant and a short plant?
Since the dominant allele in pea plant breeding is the tall allele, all of the offspring of this cross were tall. However, when he crossed two tall plants from the first filial generation, 75% of the second filial generation were tall, and 25% of the second filial generation were short, thus hinting at the mechanism of what we today recognize as genetic inheritance.
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.
When gregor mendel crossed a tall plant with a short plant the F1 plant inherited what?
one tall allele and one short allele
What did Mendel predict was a probability of producing a tall plant from a genetic cross of two hybrid tall plant?
because he is only person who predict the probability of tall and short plants is tall plant was 3 in 4 and the short plant was 1 in 4
What did mendel predict was the probability of producing a tal plant from a genetic cross of two hybrid tall piants?
The principles of probability explained the numerical results of Mendel's experiments. In one of his experiments, the probability that an F2 plant would be tall was 75%.
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 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.

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.
When gregor mendel crossed a tall plant with a short plant what did the f1 plant inherit?
They inherited a T (tall) allele from the tall parent, and a t (short) allele from the short parent. This is only if we assume that both parents are homozygous, which the short parent would need to be for the short trait to show. If this is true, then the F1 generation would show the tall trait 4/4 times, and would end up with the genotype Tt 4/4 times.
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.
