Detailed explanation-1: -In codominance, both alleles are expressed together in the offspring. If we cross a red flower and white flower that have a codominance inheritance pattern, the offspring would be flowers with red and white patches on them.
Detailed explanation-2: -incomplete dominance. All of the offspring of a red carnation crossed with a white carnation are pink. The simplest explanation for this pattern of inheritance is: The genes for hair color and skin pigmentation are linked.
Detailed explanation-3: -Codominance is also seen in plants. For example, rhododendrons with simultaneous expression of red and white genes for flower colour display flowers with both red and white petals.
Detailed explanation-4: -Figure 21: A cross between a red and white snapdragon will yield 100% pink offspring. This pattern of inheritance is described as incomplete dominance, meaning that neither of the alleles is completely dominant over the other: both alleles can be seen at the same time.
