To study the importance of the RNA telomer element, we can evaluate it by generating an in vitro state where all the purified components are included, organizing two groups, one of them will have an RNAase and the other will not, if it is observed that the telomeres extend to the component of the RNA, in the set where there is no RNAase, longer telomeres could be observed, if there were no influence of the RNA, the length in both groups would be the same
The founder effect<span> occurs when a portion of the </span>population<span> (i.e. "founders") separates from the old </span>population<span> to start a new </span>population<span> with different allele frequencies. </span>Small populations<span> are </span>more<span> susceptible </span>genetic drift<span> than large</span>populations<span>, whose larger numbers can buffer the </span>population<span> against chance events.
