100%.
The probability that a gamete produced by a pea plant heterozygous for stem height (Tt) will contain the recessive allele is 100%.
What is the probability of getting a tall pea plant phenotype when two heterozygous tall pea plants are crossed with each other?
As shown in the figure a cross between two heterozygous tall plants results in 25% homozygous tall, 50% heterozygous tall and 25% dwarf plants. Thus the correct answer is option C.
What is the probability of producing a short plant when a tall heterozygous pea plant is crossed with a tall heterozygous pea plant?
25% of the heterozygous cross are short, and the offspring of a homozygous dominant and homozygous recessive pea plant will always display the dominant trait (phenotype), because they are heterozygous.
What is the recessive gene for height in pea plants?
short gene
The tall gene is dominant in pea plants. The short gene is recessive. That is why plants with one tall gene and one short gene are always tall. Only plants with two short genes will be short.
What is the probability of producing a tall pea plant from a genetic cross between two hybrid tall pea plants?
Solution : Cross between two heterozygous tall pea plants can be shown as follows :
Hence, the probability of production of drarf offsprings is 25 % and tall offsprings is 75 %.
What is the phenotype of a pea plant with a heterozygous genotype for height?
Tall. What is the phenotype of a pea plant that is heterozygous ( Tt )? It is also tall. The answer is yes, two different genotypes can result in the same phenotype.
When a homozygous tall pea plant is crossed with heterozygous tall plant what will be the phenotypic ratio of progeny according to normal Mendelian inheritance?
Answer. Explanation: The phenotypic ratio will be 1 tall:1 dwarf.
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 would be the outcome if a homozygous tall pea plant and homozygous short pea plant are crossed?
A homozygous short pea plant will have the genotype tt. A cross between a homozygous tall tree plant and a homozygous short tree plant will give the following genotypes of the offspring: 100% Tt. Since the offspring has at least one allele that is dominant for tall trees, all the offspring will be tall.
What percentage of offspring will be heterozygous TT if one parent is homozygous dominant tall TT and the other parent is homozygous recessive short TT )?
So, the correct option is ‘50%‘.
Which law of inheritance is involved if a tall pea plant crossed with a short pea plant and produce all tall offspring?
Law of Segregation. Observing that true-breeding pea plants with contrasting traits gave rise to F1 generations that all expressed the dominant trait and F2 generations that expressed the dominant and recessive traits in a 3:1 ratio, Mendel proposed the law of segregation.
What are the two alleles for the height of a pea plant?
In pea plants, the gene for height has two alleles: tall (T) and short (t).
Why is the progeny of pea plant is always tall when a tall pea plant is crossed with a short pea plant?
(a) The cross between tall and short pea plants produces tall progeny. The tall progeny is present in heterozygous conditions and the tall trait is dominant that expresses itself and suppresses the expression of the short trait.
What is the probability of production of offspring in a cross between two heterozygous tall pea plants?
Cross between two heterozygous tall pea plants can be shown as follows : Hence, the probability of production of dwarf offsprings is 25% and tall offsprings is 75%.
What is the probability of production of the offspring in a cross between two heterozygous tall tea plant?
The correct option is C 25%
What is the probability of production of dwarf offsprings in a cross between two heterozygous tall pea plants? Q.
What is the probability of a heterozygous offspring explain your answer?
What is the probability of a heterozygous offspring? There is a 50% x 50% = 25% probability that both of the alleles of the offspring are dominant. There is a 50% x 50% = 25% probability that both alleles of the offspring’s are recessive.
What is the genotype for a pea plant heterozygous for round seeds?
Answer: Genotype of a plant pea heterozygous for round seeds and homozygous recessive for green seeds is (d) Rryy. Starting genotype of parents in a dihybrid cross would be (d) RrYy and RrYy.
What is the genotype of a heterozygous plant?
Heterozygous means that an organism has two different alleles of a gene. For example, pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white).
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‘
What is the genotype ratio for a heterozygous tall TT crossed with a heterozygous tall TT )?
Genotypic ratio = 1 TT (Homozygous tall) : 1 (Heterozygous tall); Option B is the correct answer.
What will be the phenotypic ratio of the cross between a heterozygous tall plant and a dwarf plant?
So, when a heterozygous tall plant is crossed with the dwarf plant then the progeny obtained would be in the ratio 1:1 where half of them would be tall and the other half would be dwarf.
