Cross between Pure Violet Pea Plant and Pure White Pea Plant



A monohybrid cross is a genetic cross between two individuals that differ in only one trait or characteristic. In this case, we are crossing a pure violet pea plant (VV) with a pure white pea plant (vv). The letter V represents the violet allele and v represents the white allele.



A Punnett square is a diagram used to predict the possible genotypes and phenotypes of offspring from a cross. It allows us to visualize the combinations of alleles that can occur.

To determine the potential outcomes of the cross between the pure violet pea plant and pure white pea plant, we can use a Punnett square.

The Punnett square for a monohybrid cross involves placing one parent's alleles along the top and the other parent's alleles along the side. Each box in the square represents a possible combination of alleles in the offspring.

Here is the Punnett square for the cross between the pure violet pea plant (VV) and pure white pea plant (vv):

| | V | V |
|----------|--------------|--------------|
| v | Vv | Vv |
| v | Vv | Vv |

From the Punnett square, we can see that all the offspring will have the genotype Vv, which means they will be heterozygous for the violet allele.



The genotypic ratio is the ratio of different genotypes that appear in the offspring, while the phenotypic ratio is the ratio of different phenotypes that appear in the offspring.

In this case, the genotypic ratio is 4(Vv):0(vv), as all the offspring will have the genotype Vv.

The phenotypic ratio is 4(violet):0(white), as all the offspring will have the violet phenotype.

Therefore, the genotypic and phenotypic ratios for the cross between the pure violet pea plant and pure white pea plant are both 4:0.



In a monohybrid cross between a pure violet pea plant and a pure white pea plant, all the offspring will have the genotype Vv and the violet phenotype. This is because the violet allele (V) is dominant over the white allele (v). The Punnett square helps us visualize the potential combinations of alleles and predict the genotypic and phenotypic ratios in the offspring.
