What's the difference between deme and seme?

Deme


Definition:

  • (n.) A territorial subdivision of Attica (also of modern Greece), corresponding to a township.
  • (n.) An undifferentiated aggregate of cells or plastids.

Example Sentences:

  • (1) Mass selection and random mating occurred within each deme.
  • (2) Facebook Twitter Pinterest Rendering of David L Deming’s Superman statue for Cleveland.
  • (3) The population in the chicken coop contains a relatively stable nucleus which may be organized in demes with an excess of females over males and limited territorial mobility.
  • (4) The B's may possess special adaptive properties under ecologically marginal conditions, since in a number of more 'central' demes they occur at much lowere frequencies (7-9%).
  • (5) The intensity of interdeme selection is reduced by random local extinction and colonization, and when these processes are rapid (with no selective diffusion) the expected fixation rate of spontaneous mutations with a heterozygote disadvantage approaches that in a single isolated deme.
  • (6) Much has been written about quality guru W. Edward Deming's quality improvement ideas.
  • (7) Deming (1982b) and others have espoused total system reform to achieve quality improvement--not merely altering the current system, but radically changing it.
  • (8) The joint evolution of major genes under viability selection and a modifier locus that controls recombination between the major genes, mutation at the major gene, or migration between two demes is studied.
  • (9) Levels of genetic variability, as indicated by a mean of 1.25 alleles per locus, a mean expected heterozygosity of 0.023, and a proportion of 0.25 of the loci being polymorphic, indicated limited genetic heterogeneity within and among demes.
  • (10) These demes represent one of the least genetically divergent, reproductively isolated sympatric pair of vertebrate populations that have been identified.
  • (11) It is shown that, if the migration matrix is symmetric and irreducible, the average number of sites that differ in two alleles chosen from the same deme depends only on an effective size of the whole population and not on either the elements of the migration matrix or the size of each deme separately.
  • (12) Prevalence of root caries was 23.8% in Deming and 7.3% in Lordsburg; mean number of lesions was 0.69 in Deming and 0.08 in Lordsburg (p less than 0.0001).
  • (13) The study was conducted among lifelong female residents in Lordsburg (3.5 ppm fluoride) and Deming (0.7 ppm fluoride), NM.
  • (14) (II) Treatment with the compounds with an unsaturateddelta1,2-furobenzofuranring system, such as AcO-stg, demethyl-diacetyl-stg (deMe-diAc-stg), and aflatoxin B1, resulted in nucleolar segregation and fragmentation of primary culture cells.
  • (15) The frequencies of mutant alleles at five loci were calculated for a sample of cats from the deme of Tampa, Florida.
  • (16) pipiens in Egypt was not differentiated into genetically isolated demes but, rather, seemed to consist of a single panmictic population.
  • (17) There are significant differences in growth rates between fish in the two demes, but no further morphological differentiation h-s been detected.--In light of these findings, the genetic distance between these populations is surprisingly small (Nei's I = 0.975).
  • (18) The data from comparison studies performed on five methods were analysed both by Deming's regression analysis, with calculation of the correlation coefficient, and by the difference plot.
  • (19) The present models show that interdeme selection during the spread of a mutation depends more on the capacity of the mutant to invade and become established in other demes than on selective diffusion, unless there is rapid local extinction and colonization.
  • (20) The average number of sites that differ in alleles drawn from the same and from different demes can provide some information about the degree of population subdivision, as is illustrated by using the data of Kreitman and Aquadé (1986, Proc.

Seme


Definition:

  • (a.) Sprinkled or sown; -- said of field, or a charge, when strewed or covered with small charges.

Example Sentences:

  • (1) Seme samples were obtained by masturbation after 3 days of sexual abstinence.
  • (2) Seming contradictions to other authors are discussed.
