Thus, certain genes are more efficiently transmitted to succeeding generations than other genes, so that the less favorable genes become less frequent with each successive generation. Preformationists believed that the male’s sperm carried tiny, fully developed replicas of the infant and that the female’s egg simply provided nourishment for the child before birth.
