    • In both clades, the haploid generation starts with meiosis in the diploid parent. Animals: Gametes arising through meiosis do not divide further before fertilization. Only primordial germ cells that are set aside early during development undergo meiosis. Angiosperms: Stem cells produce leaves and shoots until they switch to reproduction. Meiosis is followed by mitotic divisions to yield male (pollen grain) and female (embryo sac) gametophytes. These produce the gametes. Both clades: The haploid sperm is transferred (usually directly in animals, via pollen in plants) from its diploid male parent to the haploid egg inside the female parent. Functional integration of paternal and maternal genomes in the offspring may continue after the zygote has been formed (e.g., imprinted genes controlling early embryonic growth, delayed expression of paternal genes).
