Incomplete dominance is a type of inheritance pattern in which one allele for a specific trait is not completely dominant over the other. As a result, the phenotype of the offspring is a combination of both alleles rather than either one alone. An example of incomplete dominance is the Snapdragon flower, which is a popular ornamental flower.
What is Incomplete Dominance?
Incomplete dominance is a type of inheritance pattern that occurs when one allele for a specific trait is not completely dominant over the other. This means that the phenotype of the offspring is a combination of both alleles, rather than either one alone. In incomplete dominance, the phenotype of the offspring is a blend of the two alleles, resulting in a phenotype that is different from either parent.
Explaining Incomplete Dominance with Snapdragon Flowers
A popular example of incomplete dominance is the Snapdragon flower. This flower has two alleles for color, one for red and one for white. When the flower is bred, the offspring will have a pink flower, which is a combination of both red and white. This is because the red allele is not completely dominant over the white allele. As a result, the phenotype of the offspring is a blend of both alleles, resulting in a pink flower.
Another example of incomplete dominance is the four o’clock flower. This flower has two alleles for color, one for yellow and one for red. When the flower is bred, the offspring will have an orange flower, which is a combination of both yellow and red. This is because the yellow allele is not completely dominant over the red allele. As a result, the phenotype of the offspring is a blend of both alleles, resulting in an orange flower.
In conclusion, incomplete dominance is a type of inheritance pattern in which one allele for a specific trait is not completely dominant over the other. An example of incomplete dominance is the Snapdragon flower, which has two alleles for color, one for red and one for white. When the flower is bred, the offspring will have a pink flower, which is a combination of both red and white. Similarly, the four o’clock flower has two alleles for color, one for yellow and one for red. When the flower is bred, the offspring will have an orange flower, which is a combination of both yellow and red.
