Genetics in Action: Incomplete Dominance

In 1900, Karl Correns discovered that the traditional principles of dominance and recessiveness in genetics do not always apply. Through his experiments with four o'clock flowers, he found that crossing purebred red and white flowers resulted in pink offspring, demonstrating incomplete dominance. This concept also applies to animals, as seen in the breeding of chestnut brown and creamy white horses, producing Palomino horses. Correns' work highlighted that some gene pairs do not follow the typical dominant-recessive pattern.
