In bioinformatics, neighbor joining is a bottom-up (agglomerative) clustering method for the creation of phylogenetic trees, created by Naruya Saitou and Masatoshi Nei in 1987. [1] Usually based on DNA or protein sequence data, the algorithm requires knowledge of the distance between each pair of taxa (e.g., species or sequences) to create the ...
Masatoshi Nei was born in 1931 Japan, and his lifelong interest in biology and genetics may have its roots in his upbringing on a farm, in a family of farmers. [1] After completing his undergraduate and doctorate degrees in Japan, Nei emigrated to the United States in 1969. [ 1 ]
Nei's D A distance was created by Masatoshi Nei, a Japanese-American biologist in 1983. This distance assumes that genetic differences arise due to mutation and genetic drift , but this distance measure is known to give more reliable population trees than other distances particularly for microsatellite DNA data.
MEGA offers several approaches for testing substitution pattern homogeneity, such as composition distance, disparity index, and Monte Carlo tests. These methods are used to determine if different genetic regions evolved under the same selective pressure. Computation distance measures the variation in nucleotide composition between two sequences.
The vast majority of people whose call records have been stolen by Chinese hackers have not been notified, according to industry sources.
