|June 11, 2016
Summary
Genetic diversity in nine Russian and Mongolian sheep breeds was analyzed using ISSR-PCR. This study provides new insights into the genetic structure and relationships of sheep populations, including the Telengit and Buubey breeds.
Area of Science:
- Animal Genetics
- Molecular Biology
- Population Genetics
Context:
- The genetic structure of sheep breeds (Ovis aries) from Russia and Mongolia was investigated.
- ISSR-PCR (Inter-Simple Sequence Repeat Polymerase Chain Reaction) was employed as the primary molecular technique.
- This research includes the Telengit and Buubey sheep breeds for the first time.
Purpose:
- To examine the genetic structure of nine sheep breeds using ISSR-PCR.
- To identify species-specific and breed-specific DNA fragments.
- To assess genetic diversity, breed structure, phylogenetic relationships, and genetic distances among studied breeds.
Summary:
- ISSR-PCR analysis revealed species-specific and breed-specific DNA fragments in nine sheep breeds from Russia and Mongolia.
- Genetic diversity parameters and breed structure were assessed, with phylogenetic relationships and genetic distances determined.
- A three-tiered analysis showed variability: 15.8% between breeds, 31.4% between populations within breeds, and 52.8% among individuals within populations.
Impact:
- Provides novel genetic diversity data for Telengit and Buubey sheep breeds.
- Reconstructs the prototypal sheep gene pool using hierarchical frequency averaging.
- Offers a comprehensive understanding of sheep genetic diversity and population structure in the studied regions.

Cloning of Dolly the Sheep
8.7K
The first successfully cloned mammal was Dolly, a sheep, born on 5th July 1996 at Roslin Institute, Scotland. The cloned sheep was named after the American singer Dolly Parton. Dolly lived for seven years and died of respiratory complications, which is speculated to be due to the actual age of her DNA. Because the DNA in cloned cells belongs to an older individual, the cloned individual’s life expectancy may be affected. Indeed, analysis of Dolly’s DNA revealed shorter...

Single Nucleotide Polymorphisms-SNPs
19.6K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Comparing Copy Number Variations and SNPs
19.2K
Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Genetic Variation
1.5K
Genetic variation is the diversity in DNA sequences found among individuals of the same species. This diversity is crucial for a species' survival because it helps organisms adapt to environmental changes. Genetic variation begins with fertilization, where an egg and sperm cell merge. Each of these cells carries 23 chromosomes, up to 46 in the fertilized egg. Chromosomes are long DNA strands that contain genes, the basic units of heredity.

Gene Flow

Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.
