What are the phenotype of the f2 generation that Mendel observed?
The phenotypes present in the F1 generation depend on the phenotypes of the parental generation (and the environment). The F1 generation will display the dominant trait(s). For example, if T is tall and t is short, in the cross TT X tt the F1 generation will have the phenotype corresponding to the T allele (tall).
What was the phenotype for seed shape of both parents plants?
What percentage of the possible types of offspring had the same phenotype as the parents
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)!
Why did Mendel use all tall plants in his f1 experiment?
Mendel used all tall plants in his F1 experiment because that was the offspring from his cross of a pure tall plant and a pure short plant. By crossing two of the tall plants from F1, he proved that the recessive gene (t) was still present in the F1 generation, despite the phenotypes of all of these plants being tall. (The result of the F1 cross gave 3 tall plants and 1 short plant.)
What are the ways by which plants produce their offspring?
pollination
How do you find possible phenotypes in offspring?
The possible genotypes and phenotypes of the offspring can be determined using a Punnett square, a grid that shows the possible combinations of alleles that can result at fertilisation. The Punnett square below shows the expected genotypes of the offspring of parent pea plants that both have the genotype Rr.
How do you find possible phenotypes of offspring?
Mendel Diagrams. If the offspring gets a dominate gene from both parents, the offspring will exhibit traits from the dominate gene. If the offspring gets a dominate gene from one parent and a recessive gene from another, the offspring will exhibit traits from the dominate gene. If the offspring get a recessive gene from both parents, the offspring will exhibit traits from the recessive gene.
The offspring of two true-breeding plants is .?
When two true-breeding plants are crossed, only one result is possible.
Mendel obtained plants that were true-breeding for particular traits by what?
Selfing, self fertilization until the offspring showed not deviation from the parental stock.

You are looking at four tall pea plants What are their phenotypes and genotypes?
tall; Tt or TT
What did Medel study to learn about genetics?
Mendel studied dominant and recessive traits in pea plants and flowers that had traits that had either or phenotypes. For example, a pea plant could have round or wrinkled offspring. He would then breed the round and wrinkled together and see what happened.
What was the original generation of pea plants in Mendel's was experiment called?
P1 or parental
What did Mendel do in his second law?
The second Mendelian Law is the Law of Segregation. It states that in a cross the parental traits do not merge in the first offspring generation (ie. the recessive, "weaker" trait does not disappear for good) but instead appear unchanged in the second offspring generation. For example, if you cross homozygous dwarf pea plants to homozygous tall, all members of the first offspring generation will be tall. This makes it seem as if the dwarf trait disappears, but it does not. If you inbreed the first offspring generation, you get 25% dwarf plants in the second offspring generation. So the "lost" trait reappears.
What type of plant is the offspring of the first cross?
they are first genoratin plants offspring
