prove with the help of Mendel experiment that white flower colour W is dominant over purple colour flower w
Answers
Explanation:
-Mendel studied several different traits of a pea plant. For example, some pea plants have purple flowers and others have white flowers. Pea plants can either self-fertilize or cross-fertilize. Crossing two plants is called hybridization. To start, however, Mendel needed plants that were true-breeding. This means that after generations of self-breeding, the pea plant expressed only one version of the trait. After many generations a purple flowered plant only produced plant never produced a white flowered plant.
-Mendel then crossed a true-breeding purple flower plant and a true-breeding white flower plant. This is called a monohybrid experiment. A test cross is performed between two plants that breed true for one trait, and the resulting trait for each offspring plant is determined
-The first, true-breeding generation, is called the parent, P generation. The first generation of offspring, the first filial generation, is the F1 generation. Mendel found that these plants all had purple flowers. The F1 generation was crossed with itself. The next generation, F2 generation, had a 3:1 ration of purple to white flowers.
-If the blending hypothesis was correct, the F1 generation should have all had light purple flowers. Instead, all the F1 plants had dark purple flowers. How did Mendel explain the complete loss of the white flower characteristic in the first generation and its reappearance in the second generation?
