If we cross flowers havimg purple and violet what is colour in f¹ progeny |

Answer» violet In pea plant violet colour flower is dominant over white colour flower.When true-breeding violet flowered plants were crossed with true-breeding white flowered one, the offspring of F1 generation were all found to bear violet flowers. The trait of white colour was suppressed and violet colour trait dominated. Thus, the law of dominance was established with white flowers being the recessive trait and violet flowers being the dominant trait. It can be represented in a Punnet square, thus:In the next cross, we take the two hybrids (Vv) of the F1 generation and cross them. We find 75% of the offspring of the F2 generation show the dominant trait while 25% show the recessive trait of the parental generation. Thus, the law of purity of gametes was established. It can be represented in a Punnet square, thus: |
