An F1 x F1 cross would be a cross between heterozygous (Tt) parents. The offspring would be 1/4 TT, 1/2 Tt, and 1/4 tt. This would mean that 3/4 of the offspring would be tall, and 1/4 would be short.These offspring would be the F2 generation.

What else can I help you with?
The trait that disappeared in the f1 generation?
reappears in some plants in the F2 generation
How did Mendel find out whether the recessive alleles were still present in the f plants?
he breeded the f1 plants with a recessive homozygous plant and if the offspring (f2) showed the recessive allele, then the recessive allele is still present in the f1 plant
What did Mendel wonder about the pea plants?
Mendel wondered why traits in pea plants were passed down in certain patterns from generation to generation. He sought to understand how characteristics like flower color and seed shape were inherited and how they could be predicted in offspring. This led him to discover the basic principles of genetics.
If the alleles for traits in pea plants did not segregate during gamete formation and offspring that were recessive for a trait could be produced only by crossing two plants that where recessive?
Yes.
Why did Mendel use pure bread plants?
Mendel used purebred plants to ensure that the offspring of his experiments would have consistent and predictable traits. By controlling the genetic makeup of the parent plants, he could more easily observe and analyze the patterns of inheritance in their offspring.
What does P1 stand for in mendels theory?
P1 stands for "parental generation." This refers to the parents (mom and dad) who start off the pedigree. The P1 generation can then produce offspring (called the F1, or "first filial generation"). The F1 generation could then produce the F2 generation (or "second filial generation").
The trait that disappeared in the f1 generation?
reappears in some plants in the F2 generation
Which animal could a bulldog mate with to produce offspring?
A bulldog is a dog and can mate a dog to produce offspring .
Why did Gregor Mendel chose pea plants for experiment?
They could be used to produce many offspring quickly.
How did Mendel find out whether the recessive alleles were still present in the f plants?
he breeded the f1 plants with a recessive homozygous plant and if the offspring (f2) showed the recessive allele, then the recessive allele is still present in the f1 plant

Could 2 short haired rabbits produce a long-haired offspring?
yes
What could have been the genotypes of the two original plants what could not have been presentSuppose Mendel crossed two pea plants and got both tall and short offspring.?
It sounds like you're talking about Mendelian Genetics. ;-) If by hybrid pea you mean heterozygous, then you're look at two Aa genotypes, ya? So if you just set up your Punnett square... (Hopefully the formatting will hold) A a --------------------- A| AA Aa a| Aa AA So you get 2 phenotypes! 75% of the offspring will be tall plants (because AA, Aa, and Aa will all produce tall plants), and 25% of the offspring will be short plants (only AA can produce short plants). But if you think your plants are homozygous (AA), then you'll only get 1 phenotype, they'll all be just like the parent plants (tall)!
If the alleles for traits in pea plants did not segregate during gamete formation and offspring that were recessive for a trait could be produced only by crossing two plants that where recessive?
Yes.
Why could you say plants are a sink for oxygen?
they produce oxygen
