• "Ants, bees, and wasps (but not termites) have a peculiar genetic system called haplo-diploidy, in which females are produced sexually and have two sets of genes but males are produced asexually and have one set of genes."
• "A consequence of haplo-diploidy is that, when a female mates with a single male, her daughters have a 75% chance of sharing the same genes (because they all get the same genes from their father) rather than a 50% chance for diploid species."
• "Right away, the book stimulated a useful discussion on embryogenesis, haploidy, diploidy, gastrulation, and neurulation."
