Using Maximum Likelihood to Infer Selection from Phylogenies, this structure will be rare. The frequency of different pairs of nucleotides at each site in the secondary structure is tabulated and the algorithm is used to obtain a maximum likelihood estimate of selection strength. A map of the potential strength of selection throughout the molecule is discussed.作者: BLINK 時間: 2025-3-24 01:03 作者: 比喻好 時間: 2025-3-24 06:18

A Neutrality Test for Continuous Characters Based on Levels of Intraspecific Variation and Interspedivergence between species in DNA sequences.
