Lecture 7 : Phylogenetic Trees Reconstruction
نویسندگان
چکیده
Deoxyribonucleic Acid or DNA is commonly known to be responsible for encoding the information of life. Through sexual reproduction, DNA is passed on as hereditary material to offspring. During the replication of genes to be passed on to the offspring, sometimes ‘mistakes’ might occur. These mistakes cause the DNA, instead of being identical to the parent DNA, to change a little(one or more of the bases in the strand might have been changed). Such ’mistakes’ are known as mutations. Through many generations of reproductions, with mutations going on between every generation, bringing about little changes each time in the offspring, different species emerge(or evolve). This is where phylogenetic comes in. Phylogenetic is the study of the genetic relationship among different species.

Estimating phylogenetic trees with phangorn (Version 1.3-1)
These notes should enable the user to estimate phylogenetic trees from alignment data with different methods using the phangorn package [7]. For more background on all the methods see e.g. [2, 9]. This document illustrates some of the phangorn features to estimate phylogenetic trees using different reconstruction methods. Small adaptations to the scripts in section 6 should enable the user to p...

متن کاملTopology Selection in Unrooted Molecular Phylogenetic Tree By Minimum Model-Based Complexity Method
In reconstruction of phylogenetic trees from molecular data, it has been pointed out that multifurcate phylogenetic trees are difficult to be correctly reconstructed by the conventional methods like maximum likelihood method(ML). In order to resolve this problem, we have been engaged in developing a new phylogenetic tree reconstruction method, based on the minimum complexity principle widely us...
متن کاملPhylogenetic relationships of the commercial marine shrimp family Penaeidae from Persian Gulf
Phylogenetic relationships among all described species (total of 5 taxa) of the shrimp genus Penaeus, were examined with nucleotide sequence data from portions of mitochondrial gene and cytochrome oxidase subunit I (COI). There are twelve commercial shrimp in the Iranian coastal waters. The reconstruction of the evolution phylogeny of these species is crucial in revealing stock identity that ca...
