Single Nucleotide Polymorphisms-SNPs01:05

Single Nucleotide Polymorphisms-SNPs

13.9K
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,...

Genome-wide Association Studies-GWAS

12.4K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Comparing Copy Number Variations and SNPs

17.1K
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%...

Multi-species Conserved Sequences

3.9K
Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale  studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved...

Conservation of Small Populations02:04

Conservation of Small Populations

13.1K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Evolutionary Relationships through Genome Comparisons02:54

Evolutionary Relationships through Genome Comparisons

5.7K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Area of Science:

  • Animal genetics
  • Genomics
  • Conservation biology

Background:

  • Lanping black-boned (LPBB) sheep possess unique heritable melanin characteristics, making them valuable for medical research.
  • LPBB genetic resources are diminishing due to free grazing and crossbreeding with Lanping normal sheep (LPN).

Purpose of the Study:

  • To establish a comprehensive SNP database for LPBB sheep to facilitate genetic resource conservation and management.
  • To provide a platform for accelerating functional genomics and marker-assisted breeding studies in LPBB sheep.

Main Methods:

  • Genotype data from 100 LPBB and 50 LPN sheep were collected across 46,894,242 SNP sites.
  • Developed the Black-boned Sheep Genome SNP Database (BbGSD) with modules for LD heatmap, SNP distribution, phylogenetics, and diversity analysis.

Main Results:

  • The BbGSD database provides interactive visualization of linkage disequilibrium, SNP distribution, phylogenetic relationships, and nucleotide diversity.
  • The database integrates genotype data for effective analysis of LPBB sheep genetic resources.

Conclusions:

  • The BbGSD is the first SNP database specifically for LPBB sheep, crucial for their conservation.
  • This resource will accelerate research in functional genomics and molecular-assisted breeding for black-boned sheep.
