4 kwi 2001 · We define “biosocial” as a broad concept referencing the dynamic, bidirectional interactions between biological phenomena and social relationships and contexts, which constitute processes of human development over the life course.
29 lip 2011 · Given the Euclidean nature of the elementwise square root of phylogenetic distance matrices, the positive semidefinitiveness of the phylogenetic variance–covariance matrix of a trait following a BM model, or related models of trait evolution, can be established.
9 maj 2018 · We think we understand thee method itself but I fail to see how you go from a number of DNA-sequences to the distance matrix. I understand that the lower the number, the more related two species but on what scale is this number and how to interpret the exact meaning of this number.
Recent years have seen the birth of sociogenomics via the infusion of molecular genetic data. We chronicle the history of genetics, focusing particularly on post-2005 genome-wide association studies, the post-2015 big data era, and the emergence of polygenic scores.
17 mar 2021 · In order to understand how a distance-based model works, it is important to think about what distance means when comparing two sequences. There are three main interpretations. Nucleotide Divergence is the idea of measuring distance between two sequences based on the number of places where nucleotides are not consistent.
Distance matrices are used in phylogeny as non-parametric distance methods and were originally applied to phenetic data using a matrix of pairwise distances. These distances are then reconciled to produce a tree (a phylogram, with informative branch lengths).
24 maj 2017 · In this simulation study, we analyze the behavior of different genetic distances in Island (null hypothesis) and stepping stone models displaying varying neighborhood sizes.
