Restriction fragment length polymorphism of the rat albumin gene was discovered in a stock of Sprague-Dawley rats by Southern blots of rat liver DNAs using cloned albumin cDNA, prAlb-1 (1), as a probe. The polymorphic DNA fragments were observed when rat DNAs were digested with either Hind III or Pst 1 and the difference in length of the DNA fragments in Hind III or Pst 1 digests was estimated ...

Ten Synthetic Hexaploid Wheats (SHWs) (2n = 6x = 42, AABBDD) were analyzed using 7 Randomly Amplified Polymorphic DNA (RAPD) primers to investigate the potential genetic diversity resided within the D-genome of common wheat. Total 190 fragments were amplified in which 141 were polymorphic showing 74 % of polymorphism. Polymorphism Information Content (PIC), Genetic Similarity (GS) Coefficient, ...

Simple sequence repeats (SSRs), consisting of tandemly repeated multiple copies of mono-, di-, tri-, or tetranucleotide motifs, are ubiquitous in eukaryotic genomes and are frequently used as genetic markers, taking advantage of their length polymorphism. We have examined the polymorphism of such sequences in the chloroplast genomes of plants, by using a PCR-based assay. GenBank searches identi...

We report on likely mixed paternity in a natural population of snow skinks (Niveoscincus mirolepidotus) from alpine Tasmania, Australia. This species is nonterritorial and males guard females after copulation, suggesting that guarding behavior has evolved to prevent rival mating of still-receptive females. To what degree does this mate-guarding prevent rival copulations? We sampled gravid femal...

Free-living N2-fixing Frankia strains isolated from Casuarina sp. were investigated for genomic polymorphism. We used six 10-mer oligonucleotides as single arbitrary primers (AP) for the polymerase chain reaction (PCR) in order to amplify random DNA fragments in the genome of free-living Frankia strains. Agarose-gels of the amplified genomic DNA revealed that two of the six arbitrary primers sh...
