State Channeling of Gene Flow by Regulation of Marriage and Procreation

  • Seymour Lederberg

Abstract

The genetic makeup of an individual is dependent on the genotypes of the germ cells from whose fusion he arose. The number of different genes we carry in each cell is unknown, but is roughly estimated at between 10,000 and 100,000. Each gene may have more than one form called an allele so that we refer arbitrarily to a standard or wild-type allele and variant allele of a given gene. Our body or somatic cells generally have two representatives of each gene, one on each member of a chromosome pair. A person whose alleles for a given gene differ from each other is termed heterozygous for that gene, whereas when the alleles are the same, the person is termed homozygous wild-type or variant. This simple picture is marred by two exceptions: male humans having only one X chromosome have only one representation of the genes of that chromosome, and in either sex some genes may be duplicated extensively.
