It appears that you're discussing a genetic cross experiment involving flowers of different colors. From the information given, here's what can be inferred about the parent plants (P generation):
- There are two main color traits being discussed: purple and white.
- Purple is described as the dominant trait.
- White is the recessive trait.
When considering these details, here are possible conclusions about the parent plants' genotypes:
1. **Genotype of Purple Flower Parent:**
Since purple is the dominant trait, the purple flower parent can have one of two possible genotypes: either homozygous dominant (PP) or heterozygous (Pp).
2. **Genotype of White Flower Parent:**
White is the recessive trait, which means for a plant to exhibit white flowers, it must be homozygous recessive (pp).
Given these genotypes, we can create a Punnett square to understand the possible offspring results:
If the purple flower parent is heterozygous (Pp) and the white flower parent is homozygous recessive (pp), the cross would look like this:
```
P p
-------------
p | Pp | pp |
-------------
p | Pp | pp |
```
In this cross:
- 50% of the offspring (Pp) will exhibit purple flowers.
- 50% of the offspring (pp) will exhibit white flowers.
If the purple flower parent is homozygous dominant (PP), all offspring would be heterozygous (Pp) and exhibit purple flowers:
```
P P
-------------
p | Pp | Pp |
-------------
p | Pp | Pp |
```
In this cross:
- 100% of the offspring (Pp) will exhibit purple flowers.
Realistically, if the outcome observed includes both purple and white flowers among the offspring, it suggests that the purple parent plant is heterozygous (Pp). This is because the presence of white flower offspring indicates that the purple flower parent must have contributed a recessive allele (p).
Therefore, it can be concluded that the purple flower parent is heterozygous (Pp), and the white flower parent is homozygous recessive (pp).
April flower people in a white flower people and we're crossed the lills of the purple flowers dominant in the live for the white flowers which can be concluded about the peat parent plants
