Different mating systems may be distinguished in haploid–diploid species (reviewed in Soltis and Soltis, 1992): (1) intragametophytic selfing, in which the fusion of gametes produced by the same gametophyte results in homozygosity at all loci (Klekowski, 1973), (2) intergame- tophytic self...
Animals, with some exceptions such as males in wasps and other Hymenoptera, areentirely diploid exceptfor the haploid gametes, eggs, and spermatozoa, which are the immediate products of meiosis. What is the ploidy of Synergids? As these 8 nuclei are derived from the mitotic divisions of the h...
