Which of the following is true of double fertilization?

0 votes
    Double fertilization is a rare event in flowering plants that results in the production of two identical embryos.
    One sperm fuses with the tube cell to form the embryo, and a second sperm fuses with a generative cell to form the endosperm.
    One sperm fuses with the egg to form a zygote, and a second sperm fuses with the polar nucleus to form the endosperm.
    The first fertilization event results in the production of a zygote, and a second fertilization event occurs several days or weeks later to produce a second zygote, which degenerates to the endosperm.
