Answer 2

Genotype Determination in Pea Plants

To determine the genotypes of pea plants with round yellow and wrinkled green seeds, we can use the provided phenotypic ratios and Mendelian genetics principles.

1. Phenotypic Ratios: - The given phenotypic ratio is 1:1:1:1, which indicates a dihybrid cross involving two heterozygous traits.

2. Mendelian Genetics: - In Mendelian genetics, the dihybrid cross involves the inheritance of two different traits. - The genotypes of the parents can be determined based on the phenotypic ratios observed in the offspring.

3. Genotype Determination: - Based on the provided phenotypic ratios and the principles of Mendelian genetics, we can determine the genotypes of the pea plants as follows:

a. Parental Genotypes: - The parental genotypes can be determined by analyzing the phenotypic ratios in the offspring.

b. Offspring Phenotypes: - The observed phenotypic ratios in the offspring provide insights into the genotypes of the parental plants.

4. Conclusion: - The genotypes of the pea plants with round yellow and wrinkled green seeds can be determined based on the provided phenotypic ratios and the principles of Mendelian genetics.

Based on the information provided, the genotypes of the pea plants can be determined using the principles of Mendelian genetics and the observed phenotypic ratios in the offspring.
