Effects of Supportive Breeding on the Genetically Effective Population Size

Effects of Supportive Breeding on the Genetically Effective Population Size Division of Population Genetics Stockholm Ilniversity S-106 9 1 Stockholm, Sweden LINDA LAIKRE Division of Population Genetics Stockholm University S-106 91 Stockholm,Sweden Introduction The genetically effective population size ( N E , )is a key parameter in conservation biology, because the rate o f inbreeding ( AF),and thereby the rate of loss of genetic heterozygosity, is proportional to the inverse of the effective number (AF = 1/2Ne; e.g., Crow & Kimura 1970).
