A cross between a tall pea plant and dwarf pea plant resulted tall progenies in F1 generation, because.
When a tall pea plant is crossed with dwarf plant?
Solution : (1) The tall habit of the pea plant is dominant over the dwarf habit of the pea plant.
(2) Hence, when Mendel crossed a tall pea plant with a dwarf pea plant, the offspring obtained from this cross were all tall.
What happen when we cross the tall and dwarf varieties of garden pea?
A cross between pure breeding tall (TT) and dwarf (tt) plants produce all tall (Tt) plants in F1 progeny. These heterozygous tall plants produce 50% gametes with “T” allele and 50% with “t” allele. Random fusion of these gametes from two heterozygous tall plants gives tall and dwarf plants in 3:1 ratio.
When tall plants were crossed with dwarf plants all the plants in F1 generation were tall plants What would be the genotype of the parents?
So, the correct option is ‘1:2:1 – tall homozygous:tall heterozygous:dwarf‘.
What is the genotype of tall pea plant and dwarf pea plant?
In pea plants height is characterized by having two alleles T(tall) and t(dwarf). Since heterozygous tall pea plant (Tt is the genotype in heterozygous) is crossed with a dwarf pea plant (tt is the genotype in dwarf).
When a tall pea plant TT is crossed with dwarf plant TT What will be the F2 generation?
In F2 generation, the tall and dwarf plants will be produced in 3 : 1 ratio. Out of the three tall plants, one tall plant will be homozygous tall (TT) and two tall plants will be heterozygous tall (Tt). The dwarf plant will be homozygous (tt), as dwarfness is a recessive character.
What will be the progeny in F2 generation when pure?
Answer. Which one is a possible progeny in F2 generation of pure bred tall plant with round seed and short plant with wrinkled seeds? Right answer is D).
What happened when Mendel crossed two traits of a character in a pea plant?
Answer: Mendel also experimented to see what would happen if plants with 2 or more pure-bred traits were cross-bred. He found that each trait was inherited independently of the other and produced its own 3:1 ratio. This is the principle of independent assortment .
When Mendel crossed a tall plant and short plant?
When a tall and short plant are crossed, all of the offspring are tall. If the offspring self-fertilize, they produce tall and short plants in a ratio of 3:1 in the next generation.
When a hybrid tall pea is cross fertilized by a pure dwarf the ratio of tall to dwarf grown from the seeds will be?
So,the correct option is ‘1:1‘.
When a tall plant is crossed with a dwarf plant .what will be the ratio of tall to dwarf plants in F1 generation?
F1 generation consists of only tall plants while F2 generation has both tall and dwarf in the ratio of 3: 1.
When pure tall plant is crossed with pure dwarf plant the F1 offspring will be?
The F1 progeny produced by the crossing of pure tall pea plant with pure dwarf pea plant, is put through to self pollination, in the upcoming generation 1 homozygous tall 2 heterozygous tall 1 homozygous dwarf progeny are produced.
When a tall and dwarf pea plant were crossed F1 showed only tall plants but in F2 generation some plants were dwarf what does it mean?
Dwarf plants were not found in F1 generation, but appeared in F2 generation. This occurred due to dominance of allele responsible for tallness. The recessive alleles are expressed only in homozygous condition/similar alleles in pair (tt).
What is the genotype of dwarf plants which always produced tall offspring?
The genotype of dwarf offspring: t/t. The genotype of tall offspring: T/t whose parental cross always produce offspring.
What is phenotype in tall pea plant?
Solution: ∙ The phenotype of all the plants of F1 generation is tall. ∙ This is because all the plants have genotype – Tt, and T (Tall) is dominant to t (Dwarf).
Why in nature do we find more tall pea plants than dwarf pea plants?
Expert-verified answer
Gene for tall plant is T and dwarf plants is t. In nature, tall pea plant is found more because it is a dominant trait. Mendel came to know this when he performed cross between pure breeding tall ( TT) and pure breeding dwarf plant ( tt).
When a pure tall plant TT is crossed with a short plant TT what will be the ratio of pure tall plants to short plants in F2?
F2 Genotypic ratio =1 pure tall (TT) : 2 heterozygous tall (Tt) : 1 pure dwarf (tt); thus, the ratio of pure tall to pure short plants will be 1:1.
When pure tall plant cross with dwarf plant then percentage of tall plant is 😕
So, the correct option is ‘50%‘.
When tall and dwarf plants are crossed from which cross 1 1 ratio is obtained 1 TT and TT 2 TT and TT 3 TT and TT 4 TT and TT?
When tall and dwarf plants are crossed , from which cross `1 : 1` ratio is obtained ? When Mendel crossed a tall pea plant with a dwarf pea plant the offspring obtained from this cross were all tall.

What are the phenotypes of F2 generation?
Two phenotypes (Tall and Dwarf) are seen in F2 generation of monohybrid cross.
What is true breeding in the F2 generation?
F1 vs F2 Generations in True Breeding
True breeding involves breeding two homozygous parents. One of which is homozygous dominant and while the other is homozygous recessive.
