Analyzing Dominant Petal Color Inheritance | Red vs. White

The image shows a flower that was produced by crossing a pure red flower with a pure white flower. Which do you think is the dominant petal color: red or white? Explain.

Based on the information provided, it is not possible to determine which is the dominant petal color between red and white

Based on the information provided, it is not possible to determine which is the dominant petal color between red and white. The inheritance of traits, such as petal color, is complex and can follow different patterns.

In genetics, the term “dominant” refers to a trait that is expressed when only one copy of the gene responsible for that trait is present. Conversely, a “recessive” trait requires two copies of the gene to be expressed. However, it is important to note that dominance is not always determined by the sheer number of genes involved.

In the case of petal color, there are a few possibilities:

1. Complete Dominance: If the red color is completely dominant over white, then the resulting flower would display the red color, making the red petal color dominant.

2. Incomplete Dominance: If red and white colors mix to create a pink color, then neither the red nor the white color is completely dominant. In this case, both red and white are partially expressed, resulting in a pink petal color. In incomplete dominance scenarios, neither color is considered fully dominant.

3. Co-Dominance: It is also possible that both red and white colors are fully expressed in separate areas of the flower, resulting in petals with both red and white patches. This is referred to as co-dominance, where both traits are equally dominant and expressed together.

Determining the exact inheritance pattern could require further breeding or genetic analysis of the flower’s offspring. Without more specific information or experimental data, it is not possible to definitively determine which petal color is dominant in the given cross of pure red and white flowers.
