In addition to the active digestion of male organelle nuclei by the nuclease, the difference in size between male and female gametes in anisogamous and oogamous organisms indicates that the contribution to the progeny of male organellar genomes (DNA) is small, while that of female gametes is large, suggesting that anisogamy and oogamy reinforce maternal inheritance.
This conflict begins with the investment in the size of male and female gametes (anisogamy, Trivers 1972) and continues with the conflict over the number of matings (Bateman 1948).
Likewise, sexual selection has been implicated in the evolution of egg size, anisogamy, and egg accessory coats (Levitan, 1998, 2004).
