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.
