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.
What is the genotypic ratio of plants in F2 generation when a tall pea plant TT is crossed with a dwarf pea plant TT )?
So, the correct option is D. 1(TT) : 2(Tt) : 1(tt)
What is the genotypic ratio of F2 generation in pea plants?
1 : 1. Was this answer helpful?
When a tall pea plant is crossed with dwarf plant what will be the F2 generation?
From the table above we can infer that the ratio of dwarf plants in F2 generation will be 25%.
What is the ratio of tall and dwarf plant in F2 generation?
3:1
Phenotypic ratio- 3:1 (3 Tall:1 dwarf)
What is the ratio of the plants in F2 generation?
Detailed Solution. The phenotypic ratio in the F2 generation is 9 : 3 : 3 : 1.
What is the ratio of the tall pea plants to short pea plants?
3:1
The usual ratio of 3:1 is for “all” tall plants to short plants.
What percentage of the F2 generation had the genotype TT?
| Parent Pea Plants (Two Members of F1 Generation) | Offspring (F2 Generation) | |
|---|---|---|
| Genotypes: Tt x Tt | Phenotypes: tall x tall | Genotypes: 25% TT 50% Tt 25% tt |
When TT is crossed with TT the genotypic ratio is F2 generation is?
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.
What is the genotype of F2 generation?
The F2 generation is more diverse, as the result of crossbreeding two heterozygous parents. The genotype distribution of the F2 generation is 25% homozygous dominant, 50% heterozygous, and 25% homozygous recessive.
When a tall plant TT in pea is crossed with another tall plant TT the probability of obtaining a dwarf plant is?
This is because the heterozygous plant will make two types of gametes, one type having T allele and the other having t allele. Hence, the correct answer is ‘1 tall : 1 dwarf‘
When a tall plant TT is crossed with a dwarf plant what percentage of the offspring will be dwarf?
So, the correct option is ‘50%‘.
When a tall plant TT is crossed with a short plant TT What is the result?
When a pure tall plant (TT) is crossed with the pure short plant (tt), then the progeny in the F1 generation will be hybrid (Tt). When the F1 generation is self-crossed (Tt), then in the F2 generation, the progeny produced will be tall homozygous (TT), Tall heterozygous (Tt), and dwarf homozygous in the ratio of 1:2:1.
What is the ratio of hybrid tall to pure tall plants in F2 progeny?
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).
What is the ratio of homozygous tall and heterozygous dwarf plant in F2 generation?
1(homozygous dominant): 2(heterozygotes):1 (homozygous recessive).
When a pure tall plant TT is crossed?
This shows that ratio of pure tall (TT) to pure short (tt) is 1:1.
What will be the ratio of tall and dwarf plants in the F2 generation when a homozygous tall plant is crossed with homozygous dwarf plant?
The selfing of heterozygous tall plants yields F2 generation with the genotypic ratio of 1 TT (homozygous tall): 2 Tt (heterozygous tall): 1 tt (homozygous dwarf). Thus, the correct answer is option B.
What is the percentage of heterozygous tall pea plants in F2 generation?
50% heterozygous
50% heterozygous tall pea plants would be obtained in F2 generation when tall heterozygous pea plants are selfed.
What is the ratio of plants in F2 generation in dihybrid cross?
In a mendelian dihybrid cross, the ratio among homozygous dominant (RRYY), pure heterozygous (RrYy) and homozygous recessive (rryy) traits in F2 generation in a pea plant is 1:4:1.
What is the ratio of tall and short plants in F1 generation?
F1 generation will be all Tt (tall plant). Thus, the ratio of pure tall plants (TT) to pure short plants (tt) is 1:1.
What are the genotypes of a homozygous and a heterozygous tall pea plant?
Thus, if the result is all tall plants then the genotype of the parent will be homozygous dominant (TT) and if the result is 50% tall and 50% dwarf then the parent will be heterozygous dominant (Tt).
