Medical Definition of Anisogamy

1. A condition where the gametes of a species have different sizes. In general, the smaller, more mobile gamete is male and the larger one which is packed with food and other things to give the potential zygote a good start (and is less mobile as a result) is the female. The principle behind anisogamy is a division of the labour necessary for two gametes to unite and successfully develop. (09 Oct 1997)
