Article Abstract:
The extent of genetic variation within and between 12 lines of chickens of different origins was investigated using a DNA fingerprinting technique. Genetic variation estimation indicated that genetic variability was highest in the commercial broiler line and lowest in the White Leghorn inbred line. The three measures of genetic variation within populations provided results that were highly correlated. Phylogenetic trees and coefficients of correlations showed a lower degree of correspondence for the estimation of genetic variation between populations by three different methods.

Article Abstract:
A study of DNA fingerprinting in Japanese Black cattle suggests that it can be applied in the estimation of the relationship coefficient in other species besides cattle. A new method for evaluating heterozygous minisatellite loci proposed the estimation of genetic similarity by the land sharing (BS) method and a new evaluation called genetic similarity (GS). An accurate estimation of the relationship coefficient can be obtained by utilizing other minisatellite probes and restriction endonucleases.

Article Abstract:
DNA fingerprinting analysis indicates that five genetically different lines of homozygous clonal rainbow trout are genetically isogenic to each other. Gametes from androgenetic male and female rainbow trouts are used to produce homozygous clones. The inheritance of markers indicates the homozygosity of parents and the absence of germ line mutations. Crossing homozygous females and males of different strains produce hybrid clones. The characteristics of DNA fingerprinting are discussed.
