Final answer:
In the case of flower color inheritance, such as in hibiscus, the phenomenon of incomplete dominance can lead to offspring exhibiting intermediate colors, like pink, resulting from the crossing of red and white flowers. The offspring could potentially show a genotypic ratio of 1 CRC:2 CCW:1 CWCW, corresponding to a phenotypic ratio of red:pink:white.
Step-by-step explanation:
When a red hibiscus is crossed with a white hibiscus, the color produced may not be a simple blend of red and white.
This is because flower color inheritance can exhibit a pattern known as incomplete dominance.
In incomplete dominance, the resulting offspring may show an intermediate phenotype which is not identical to either parent but a mixture of both.
For instance, crossing a homozygous red-flowered plant with a homozygous white-flowered plant might yield offspring with pink flowers, where the pink color is due to the dilution of the red pigment in the presence of the white background of the petals.
The genotypic ratio for a cross of heterozygotes in this case would follow the pattern 1 CRC:2 CCW:1 CWCW, which translates to a phenotypic ratio of 1:2:1 for red:pink:white flowers.
This is due to the incomplete dominance of the red allele over the white allele.
It's important to note that other genetic factors and environmental conditions can also influence the expression of flower color, making the actual outcome potentially more complex.
