A red flowered plant is crossed with a white flowered plant, all of the offspring are pink
Problem 10: Disappearance of parental phenotypes in the F1 generationA genetic cross of inbred snapdragons with red flowers with inbred snapdragons with white flowers resulted in F1-hybrid offspring that all had pink flowers. When the F1 plants were self-pollinated, the resulting F2-generation plants had a phenotypic ratio of 1 red: 2 pink: 1 white. The most likely explanation is: Show

Explanation:Incomplete dominance is an example of a non-mendelian trait (doesn't follow the genetic rules established by Gregor Mendel). When two parents mate and produce offspring, the offspring is a blend of the two parents. So, a red flower and a white flower would make a pink flower. What is the color of the flower when a plant with red flower is crossed with a plant with white flower?When a red flowered plant is crossed with a white flowered plant, ideally the offsprings should bear either red and white flower. However, in the case where the trait flower color exhibits incomplete dominance, all the offsprings will give forth pink colored flowers due to the blending of traits.
When a red flower is crossed with a white flower The ratio of red and white Coloured plants in F2 generation will be?When red coloured flowers crossed with white coloured flowers are giving an F2 ration of 3:1, it ensures that the red colour is dominant. In the case of co-dominance, the F2 produced will have pink flowers along with white and red flowers.
What will be the ratio of offspring in a cross between red flowers and pink flower of Mirabilis?So, the correct answer is '50% pink and 50% red'.
What are the chances of appearance of red flowered plants in a cross between pink and white flowered plant of antirrhinum?What are the chances of appearance of red flowered plant in a cross between pink and white flowered plant? In Mirabilis, red flowered plant crossed with white flowered one resulted in all pink flowered plants.
