Abstract

BY ATAM VETTA” AND CEDRIC A. B. SMITH Galton Laboratory, University College, London It is well known that mating is not appreciably influenced by characters such as blood groups, biochemical characters, and similar ones which have no visible effect. That is to say, most polymorphic characters which have a simple Mendelian inheritance will not show assortative mating. Of course, rare Mendelian characters with severe effects often will influence mating. But as they are so rare, they will have a negligible effect in the population as a whole. I n contrast to this there is strongly assortative mating in a number of physical and intellectual characters such as height and intelligence. These are believed to have a t least in part a multifactorial genetic basis. The original and classic paper taking into account the effect of assortative mating on Mendelian inheritance was that of Fisher (1918). Several other papers have been written and a recent one by Wilson (1973) claims that Fisher was mistaken, or a t any rate that Fisher’s results were only compatible with a ‘one-sided model’ of selection, in which one spouse chose the other. She proposed to replace this by a new ‘two-sided’ model, within
