heterogamy
Quick Summary
Heterogamy, also known as anisogamy, is a form of sexual reproduction involving the fusion of gametes that differ in size, structure, or physiology. This contrasts with isogamy, where gametes are identical. In animals and higher plants, a common form of heterogamy is oogamy, where a small, motile sperm fuses with a large, non-motile egg. This difference in gamete size is thought to have arisen through disruptive selection, favoring smaller, more mobile gametes and larger, resource-rich gametes over intermediate forms.123
