Sperms and eggs contribute equal numbers of genes, but eggs contribute far more in the way of food reserves

“Sperms and eggs contribute equal numbers of genes, but eggs contribute far more in the way of food reserves: indeed, sperms make no contribution at all and are simply concerned with transporting their genes as fast as possible to an egg. At the moment of conception, therefore, the father has invested less than his fair share (i.e. 50 per cent) of resources in the offspring. Since each sperm is so tiny, a male can afford to make millions of them everyday. This means he is potentially able to beget a very large number of children in a very short period of time, using different females. This is only because each new embryo is endowed with adequate food by the mother in each case. This therefore places a limit on the number of children a female can have, but the number of children a male can have is virtually unlimited. Female exploitation begins here.”
