Answers

In this context, we have two alleles for flower color: purple (dominant) and white (recessive). The genotypes you provided indicate the following:
- **PP**: Homozygous dominant (purple flowers)
- **Pp**: Heterozygous (purple flowers)
- **pp**: Homozygous recessive (white flowers)
According to Mendelian genetics:
- The **dominant trait** (purple flowers) will be expressed in both PP and Pp individuals.
- The **recessive trait** (white flowers) will only be expressed in pp individuals.
If you want to know the expected phenotypic ratios from a cross involving these genotypes, here are a couple of examples:
1. **Cross between PP and pp**:
- Offspring: 100% Pp (all purple flowers)
2. **Cross between Pp and pp**:
- Offspring: 50% Pp (purple) and 50% pp (white)
3. **Cross between Pp and Pp**:
- Offspring: 25% PP (purple), 50% Pp (purple), and 25% pp (white), leading to a phenotypic ratio of 3:1 (purple: white).
If you have a specific cross in mind or any particular question, feel free to ask!
