Document Summary
Much of it consists of huge numbers of repeated sequences. Most noncoding variaion; we sill don"t know whether is has any efect. Each neutral allele has an equal change of being the one that will eventually become. Ixed via geneic drit (i. e. reach 1--% frequency in the populaion) If the frequency of allele a is 0. 15, then the probability it will eventually become the only allele of the populaion is 0. 15. Populaion size afects the dynamics of neutral allele frequency change. Or many none of these? (i. e. nothing interesing) Hardy-weinberg principle: in a freely interbreeding, sexually reproducing populaion, the frequency of each allele remains constant. A null hypothesis is a default, placed along side a (usually) more interesing hypothesis. If the null hypothesis cannot be demonstrated to be false, then the more interesing hypothesis is not adopted. If the data appear to conform to the hw predicions, then the null hypothesis is adopted.
