Question

Answer

Answer

Answer

Explanation:

Genotype and Phenotype:

- Genotype refers to the genetic makeup of an organism, while phenotype refers to the physical characteristics or traits of an organism.
- In this case, VV represents the genotype for violet flowers, and vv represents the genotype for white flowers.
- The phenotype of the F1 progeny will depend on the combination of alleles inherited from the parent plants.

Punnett Square:

- To determine the possible genotypes and phenotypes of the F1 progeny, we can use a Punnett square.
- A Punnett square is a grid used to predict the possible genotypes and phenotypes of offspring based on the genotypes of the parent plants.
- In this case, since both parent plants have different genotypes (VV and vv), we can create a Punnett square with the corresponding alleles.

Possible Genotypes and Phenotypes:

- When we cross VV and vv, the resulting Punnett square will show that all of the offspring will have the genotype Vv.
- This is because the V allele is dominant over the v allele, meaning that even if only one V allele is present, the phenotype will be violet.
- Therefore, the F1 progeny will have the genotype Vv, which means they will all have violet flowers.
- The correct answer is option A: All violet; Tt.

Key Points:
- The genotype refers to the genetic makeup of an organism, while the phenotype refers to the physical characteristics or traits.
- The Punnett square is a tool used to predict the possible genotypes and phenotypes of offspring.
- In this case, crossing VV and vv will result in all F1 progeny having the genotype Vv.
- The V allele is dominant over the v allele, so the phenotype of all the F1 progeny will be violet.
- Therefore, the correct answer is option A: All violet; Tt.
