In a given plant, redcolour(R) of fruits is dominant over white fruit ...
In order to determine the percentage of tall plants with red fruits in the next generation, we need to understand the principles of Mendelian genetics and the inheritance patterns of the given traits.
Mendelian Genetics:
- Gregor Mendel was a scientist who conducted extensive experiments on pea plants and formulated the principles of inheritance.
- According to Mendel's laws, an individual inherits two copies of each gene, one from each parent. These copies are called alleles.
- Alleles can be either dominant or recessive. Dominant alleles are expressed in the phenotype, while recessive alleles are only expressed when there are no dominant alleles present.
Inheritance of Traits:
- In the given plant, red color (R) of fruits is dominant over white fruit (r), and tallness (T) is dominant over dwarfness (t).
- When a plant with genotype RRTt is crossed with a plant of genotype rrtt, we need to determine the possible combinations of alleles in the offspring.
Possible Gametes:
- The plant with genotype RRTt can produce gametes with the following combinations of alleles: RT and Rt.
- The plant with genotype rrtt can produce gametes with the following combinations of alleles: rt.
Punnett Square:
To determine the possible genotypes and phenotypes of the offspring, we can use a Punnett square.
| R T | R t |
-----------------------------------
r t | RtTt | rtTt |
r t | RtTt | rtTt |
-----------------------------------
- From the Punnett square, we can see that 50% of the offspring will have the genotype RtTt, which represents tall plants with red fruits.
- Therefore, the percentage of tall plants with red fruits in the next generation is 50%.
Therefore, the correct answer is option C) 50%.

Possible Gametes:
- The plant with genotype RRTt can produce gametes with the following combinations of alleles: RT and Rt.
- The plant with genotype rrtt can produce gametes with the following combinations of alleles: rt.
Punnett Square:
To determine the possible genotypes and phenotypes of the offspring, we can use a Punnett square.
| R T | R t |
-----------------------------------
r t | RtTt | rtTt |
r t | RtTt | rtTt |
-----------------------------------
- From the Punnett square, we can see that 50% of the offspring will have the genotype RtTt, which represents tall plants with red fruits.
- Therefore, the percentage of tall plants with red fruits in the next generation is 50%.
Therefore, the correct answer is option C) 50%.

In a given plant, redcolour(R) of fruits is dominant over white fruit ...
According to question, tallness (T) is dominant over dwarfism (t) and red colour (R) is dominant over white (r) fruit colour.
Parent Generation; P1 : RRTt x rrtt
F1 generation :
Phenotypic ratio = 1 (tall plant, red fruit)
: 1 (dwarf plant, red fruit)
; thus, percent of tall plant with red fruit is 50%.
Phenotypic ratio = 1 (tall plant, red fruit)
: 1 (dwarf plant, red fruit)
; thus, percent of tall plant with red fruit is 50%.
