    • ‘Bryophytes reproduce through syngamy and meiosis, but the dominant stage of the plant is the gametophyte, as opposed to the sporophyte in vascular plants.’
    • ‘Any reproductive process that does not involve meiosis or syngamy is said to be asexual, or vegetative.’
    • ‘Within a sexual population, however, the segregation of alleles would break down the genetic association, and the less fit homozygotes would be formed by syngamy each generation.’
    • ‘We describe the maternal and paternal contributions to the diploid cell by reminding the students of the origin of a diploid cell and the process of syngamy that follows fertilization.’
