14 kwi 2021 · Results: Our results show a strong inverse relationship, i.e. 88.6% of the variation in the overall genetic diversity of domesticated chicken populations was explained by their genetic distance to the wild populations. We also investigated whether the patterns of genetic diversity of different types of single nucleotide polymorphisms (SNPs) and ...
16 sty 2020 · We evaluated genetic diversity in a principal component analysis (PCA) of the genetic relatedness matrix between Thoroughbreds and representatives of putative founding populations and within...
Bone samples of ancient horses from different cultures of Altai were investigated to clarify the genetic history of this horse breed. As a genetic marker, we chose hypervariable region I of...
Sets of tuples are intersected to calculate the distance between species. These distances are then added to a distance matrix that can be used to recover phylogenies.
16 cze 2021 · Identification of high-impact mutations. To measure whether the domestication-associated bottleneck could have induced the rise of high-impact SNPs (hSNPs) in chicken genomes, we analyzed the variants called in domestic chicken and GGS genomes among our 1K CGP.
The aim of the current study was to evaluated genetic diversity, relationship and population structure of Saudi native chicken breeds based on 20 microsatellite markers.
A mutational model allows corrected distances. Jukes-Cantor model: D = 3 4 ln (1 4 3 Ds) D is the corrected distance (what we want) Dsis the raw count (what we have) ln is the natural log. Mutational models for DNA. Jukes-Cantor (JC): all mutations equally likely Kimura 2-parameter (K2P): transitions more likely than transversions Felsenstein ...
