Answer:
Hello, this is Bing. I can help you with this biology question. Here is my answer:
The blending theory of heredity was an early attempt to explain how traits are inherited from parents to offspring. It proposed that the traits of the parents are mixed or blended in the offspring, like mixing paints of different colors. For example, a cross between a red flower and a white flower would produce pink flowers, which are a blend of red and white.
According to the blending theory of heredity, a cross between a red flower and a white flower would produce only pink flowers as offspring. The pink flowers would then produce more pink flowers when crossed with each other or with red or white flowers. The original red and white traits would be lost in the blending process.
However, the blending theory of heredity is incorrect and has been disproved by many experiments and observations. The modern understanding of genetics shows that traits are determined by discrete units called genes, which are inherited from parents to offspring in specific patterns. For example, a cross between a red flower and a white flower could produce red, white or pink flowers, depending on the genes and how they are expressed.
