How could the f1 generation of tall offspring produce 3 tall plants and 1 short?

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.

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
The trait that disappeared in the f1 generation?
reappears in some plants in the F2 generation
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.
If each of the offspring were allowed to self fertilize What are the possible genotypes in the next generation?
depends how it self fertilises. If the gametes are produced with random genes in them the offspring could have recessive charateristics not displayed on the parent. However it could only have charateristics that were present in the parents genotype to begin with. If the offspring has the same genotype as tha parent then it would be the exact same.
What will mutation do if it does not occur in sex cells?
Mutations which do not occur in sex cells are not passed on to the next generation. The mutation will only affect the individual. They could therefore have normal 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").
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.

Would animal could a bulldog mate with to produce offspring?
another bulldog.
Which animal could a Siamese cat mate with to produce offspring?
another cat

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)!
Could 2 short haired rabbits produce a long-haired offspring?
yes
Why did Mandel choose peas for his experiment?
They could be used to produce many offspring quickly.
Why could you say plants are a sink for oxygen?
they produce oxygen
