A certain plant homozygous for yellow seeds and red flowers was crossed with a plant homozygous for green seed

Question

A certain plant homozygous for yellow seeds and red flowers was crossed with a plant homozygous for green seeds and white flowers. The F1 plants had yellow seeds and pink flowers. The F1 plants were selfed to get F2 progeny. Assuming independent assortment of the two characters, how many phenotypic categories are expected for these characters in the F2 generation?

Accepted Answer

This problem involves two distinct inheritance patterns. 
1. Seed Color: The cross produces yellow seeds in F1, indicating complete dominance of Yellow over Green. In the F2 generation, this yields 2 phenotypes (Yellow and Green) .
2. Flower Color: The cross produces pink flowers from red and white parents, indicating incomplete dominance. In the F2 generation, this yields 3 phenotypes (Red, Pink, and White) .
3. Independent Assortment: According to the Law of Independent Assortment, the traits segregate independently. The total number of phenotypic categories is the product of the phenotypes for each trait:  phenotypic categories .
