Genetic Structure and Differentiation of Four Populations of Afghan Pika (Ochotonarufescens) based on mitochondrial cytochrome b gene in Iran

In 2012, Rin et al. 2010). The main and negative result of Fs shows that there was at least one population increase in the past. Network analysis supports this hypothesis in star system development. The development of the star system is the result of a sudden increase in the population (Slatkin and Hudson 1991, Rogers and Harpending 1992, Yu et al 2012). In ML phylogenetic tree and network analysis, all the samples were compiled into three major groups (Figure 2) and genetically separated from each other based on the current conditions.

Little et al. In 2013, we estimated the genetic diversity and genetic differentiation between Wb populations using the Wb mitochondrial gene cytochrome oxidase 1 (COX 1) (Small et al., 2013). They determined and cloned the COX1 gene sequence from 16 Wb-infected individuals selected from 7 villages. Each village is highly likely to be infected by middle-aged and elderly people. In the 487 sequence, they observed 203 unique COX1 haplotypes with a single haplotype in 93% of all infections. Like Kumar et al. They observed a high genetic variation within the genome and up to four times the diversity among the infections of 4 individuals. Unlike previous studies in India, they did not find any significant genetic differences between the populations, but instead distributed the majority of the mutations within the population. Instead, it is recommended that advanced immigration between recently mixed places or sampled places have similar infections. Finally, Small et al.

Genetic markers are often used to track the origin of a population and to understand the structure and dispersion mechanism of the population. Sequence-based mitochondrial DNA (mtDNA) is commonly used to infer demographic history such as founder events and demographic expansion related to colonization after cold. Meanwhile, frequency-based markers such as microsatellites and AFLP detect the recent subtle differences among populations and investigate how ecological factors affect the distribution of modern genetic variation It is commonly used. However, genetic structure does not necessarily reflect gene flow, as many populations are not in a migration-drift equilibrium state. The genetic structure is the result of a superposition of modern gene flow levels against systematic geographical and demographic history.

Similar mitochondrial cell lineage is shared. Modern Native Americans share genetic strains with North Asians, but they are different from most other populations. These lines are considered to be distinguished from each other at a rate of about 2% to 3% per million years. In the mid-1990s, Emory University anthropologist Theodore Schurr used these calculations to determine how long since the division of the old world and the new world population. If his calculations were correct, splitting occurred between 20,000 and 40,000 years ago.
