Relationship between DNA polymorphism and fixation time.

Relationship Between DNA Polymorphism and Fixation Time Fumio Tajima

When there is no recombination among nucleotide sites in DNA sequences, DNA polymorphism and fixation of mutants at nucleotide sites are mutually related. Using the method of gene genealogy, the relationship between the DNA polymorphism and the fixation of mutant nucleotide was quantitatively investigated under the assumption that mutants are selectively neutral, that there is no recombination ...

the relationship between critical thinking and reading strategies

during the process of reading, sometimes learners use ineffective and inefficient strategies and some factors may influence their use of strategies. perhaps critical thinking is one of these factors. this study aims to identify those categories of reading strategies that are mostly used by iranian efl learners and to see if there is any significant relationship between the critical thinking abi...

Relationship between migration and DNA polymorphism in a local population.

The expected amount of DNA polymorphism, measured in terms of the number of nucleotide differences between the two DNA sequences randomly sampled from subpopulations, was studied by using the stepping-stone model and the finite island model, under the assumption that the migration rate is not the same among different subpopulations. The results obtained indicate that the expected amount of DNA ...

the relationship between collocational competence and listening comprehension

پس از پیدایش روش تدریس ‏‍tpr توسط جیمز اشر که توجه و تآکید بسیاری بر مهارت شنیداری داشت زبانشناسان همواره در صدد یافتن راههایی برای بهبود این مهارت در زبان آموزان می باشند. از طرفی جی-آر-فرث که از پیشگامان زبانشناسی می باشد بر تآثیر لغات و بویژه گروه کلمات که اغلب در گفتار با هم می آیند (هم آیی کلمات)تأکید بسیار کرده است. به این دلیل و به منظوربررسی رابطه بین این دو عامل یعنی درک شنیداری و دانش...
