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 probability of producing a tall pea plant when a heterozygous tall pea plant is crossed with a homozygous short pea plant?
Since 1 out of 4 pea plants are short, or 1/4, the probability of a short pea plant from a heterozygous cross is 25% .
What is the probability of production of homozygous tall offspring in a cross between two heterozygous tall pea plants?

What is the probability of a tall plant?
75% is the probability of producing a tall plant from two hybrid tall plants. Explanation: Each hybrid tall plant will have two genomes- T and t. So when two such plants are crosses, every gametes that is formed has the genomic form of TT, Tt or tt.
What is production probability?
Probability in Manufacturing
Probability applies to manufacturing in numerous practical instances . ... Other instances of probability in manufacturing include determining the likelihood of producing defective products, and regional need and capacity for certain fields of manufacturing.
Which of the following crosses will give tall and dwarf pea plants in same proportions?
- A.
- B.
- C.
- D.
- Answer. B.
- This is an example of a test cross in which a cross is made between heterozygous tall and homnozygous dwarf individuals, tall and dwarf plants are obtained in same proportions. .
How would you test a pea plant whether it is pure or hybrid for tallness?
Complete answer: The tallness trait of the pea plant may have a homozygous or heterozygous genotype. The dwarf plant has a homozygous genotype. In order to determine whether the pea plant is homozygous tall or heterozygous tall, it needs to be crossed with the dwarf plant .
What kind of offspring would a cross between two heterozygous tall pea plants give?
A cross between two heterozygous tall plants, it will result in 25% homozygous tall (TT), 50% heterozygous tall (Tt) and 25% short plants (tt) . Phenotype: 75% tall, 25% short. Hope this helps!!
When a plant homozygous for tall is crossed?
ANSWER: The condition given is that a plant ( Homozygous tall) is crossed with a plant ( Homozygous dwarf), then the appearance of the plats or saplings at the F1 generation would be all tall plants . The plants are homozygous tall , so their alleles will be the same.
What is heterozygous tall?
Heterozygous tall (Tt) is crossed with homozygous tall (tt) . Percentage of heterozygous tall in the progeny would be. ... Hint: Heterozygous is a condition when there are two different traits of a particular gene. When a dominant character has to be expressed both the letters are capital.
What is the probability of producing a tall pea plant?
| A B | The different forms of a gene are called alleles. | What is probability? a number that describes how likely it is that an event will occur | What is the probability of producing a tall pea plant from a genetic cross between two hybrid tall pea plants? three in four |

What is the probability that the offspring plant will be short?
Using a punnet square, four possible offsprings with phenotypic ratio of 3:1 will be produced i.e. 3 tall plants to 1 short plant. Hence, the probability that a plant will be short (tt) is 1/4 or 0.25 .
What happens when two homozygous plants are crossed?
When true-breeding, or homozygous, individuals that differ for a certain trait are crossed, all of the offspring will be heterozygous for that trait .
When tall and dwarf plants are crossed from which cross 1 is to 1 ratio is obtained?
The ratio obtained between the homozygous tall and homozygous dwarf is 1:1. Thus, the correct option is B. i.e. 1:1.
How can you determine the genotype of a tall plant at F2 generation?
Dihybrid cross. Hint: Gregor Mendel chose pea plant to show that genotypic and phenotypic expression of the traits. He made many crosses to know the expression of traits of each level. To determine genotype of F2 generation, he crossed dominant trait with recessive parent to check the unknown genotype .
Which of the following is test cross?
A test cross is a cross between heterozygous F1 hybrid and double recessive homozygous . e.g., Tt×tt to show whether F1 is homozygous or heterozygous.
