In four o’clock plants, many flower colors are observed. In a crossinvolving two true-breeding strains, one crimson and the otherwhite, all of the F1 generation were rose color. In the F2, four newphenotypes appeared along with the P1 and F1 parental colors.The following ratio was obtained: 1/16 crimson2/16 orange1/16 yellow2/16 magenta4/16 rose2/16 pale yellow4/16 white Propose an explanation for the inheritance of these flowercolors.

Angiosperm Reproduction

The process of sexual reproduction in flowering plants is known as angiosperm reproduction. In flowering plants, reproduction begins with pollination, or the transfer of male gametes (pollen) from the male reproductive organ (anther) to the female reproductive organ (pistil), and ends with fertilization of the female gametes (egg), which produces a zygote, which then grows to become a mature plant.
