determine sex. In the simplest case, the male germ cells
     are of two types, one with and one without a single extra
     chromosome (X chromosome, or monosome). The egg cells
     in this case all possess an X chromosome, and on fertili-
     zation by the two types of sperm, male and female zygotes
     result, of respective constitution X, and XX. In many
     other animals and plants (probably including man) the
     male organism produces two types of gametes, one pos-
     sessing an X chromosome, the other a Y chromosome,
     these being visibly different members of a pair of chromo-
     somes present in the diploid state. In this case also, the
     female organism is XX, the eggs X, and the zygotes re-
     spectively male (XY) and female (XX). In another type of
     sex determination, as in certain moths and possibly in the
     fowl, the female produces two kinds of eggs, the male only
     one kind of sperm. Each type of egg contains one member
     of a pair of differentiated chromosomes, called respec-
     tively Z chromosomes and W chromosomes, while all the
     sperm cells contain a Z chromosome. In fertilization, un-
     ion of a Z with a W gives rise to a female, while union of
     two Z chromosomes produces a male. Cf. SECONDARY SEX
