genetic variability 中文意思是什麼

genetic variability 解釋
遺傳變量性

  • variability : n. 易變,變化性;【生物學】變異性。
  1. As analyzed, ( 1 ) the rapd technique is highly sensitive to investigating genetic diversity in t. lepturus and e. muticus. t. lepturus exhibits lower polymorphism and genetic diversity than e. muticus ; ( 2 ) according to the analysis of the partial mitochondrial 16s rrna gene sequences, a very low intraspecific variation and considerably high divergence among species were found, which reveals a dual nature of conservatism and variability in mitochondrial 16s rrna gene ; ( 3 ) five primers generate the species - speeific rapd sites and these sites can be served as the molecular markers for species identification and ( 4 ) it can be proved at dna variation level that t. lepturus and e. muticus are of two species respectively pertainiag to different genera, which supported the nelson taxonomic conclusion

  9. The paper summarizes study progress of molecular conservation genetic from the following respects : measuring and managing genetic diversity and genetic variability within populations. identifying of evolution distinct populations, defining the appropriate geographic scale to monitor and manage genetic structure and gene flow. defining management units and the recognition of evolutionarily significant units. multiplying and conserving of in - situ conservation species and ex - situ conservation species

    然而散播得最廣、最遠的例子,可能是我們味覺的變異。
  11. The percentage of specific polymorphic loci ( spb ) was 70 %, and the percentage of population polymorphic loci ( ppb ) varied from 14 % to 20 %. and hn population amount was the highest ( 20 % ), whereas the jx population was the lowest ( 14 % ), which indicated low genetic diversity within population and little variability among populations. 2
