What are variations in specific nucleotides that are linked to human diseases called?
Single nucleotide polymorphisms which are also called SNPs or snips.
How many SNPs does the average human genome have?
Apparently around 1-2 million but its going to vary hugely from individual to individual, from ethnic group to ethnic group. 1.42 Million In genic regions, the SNP density in intronic, exonic and adjoining untranslated regions was 8.21, 5.28, and 7.51 SNPs per 10 kb, respectively. The average here would be 2.1million
What types of DNA do scientists use to determine individual identities of organisms within the same species?
Single nucleotide polymorphisms (SNPs) and short tandem repeats (STRs)
What is a list of the types of genetic testing?
There are three types of genealogical DNA tests, autosomal (atDNA), mitochondrial DNA. A list of single nucleotide polymorphisms (SNPs) is returned.
What is the most common type of mutation?
A point mutation (transition) that changes A-G or C-T. 2/3 of SNPs are transitions.
What do the SNPs do in Scotland?
They form the Government.
Out of a total 3 billion base pairs within the human genome how many are SNPs?
2.8 billion
What are variations in specific nucleotides that are linked to human diseases called?
Single nucleotide polymorphisms which are also called SNPs or snips.
How can you tell if you have haplogroup H-M82?
If you are a man, you will have to do a DNA test that looks at the SNPs on your Y chromosome. One that I've used is www.britainsdna.com
What is SNPs?
Single nucleotide polymorphisms:SNP is a DNA sequence variation occurring when a single nucleotide - A, T, C or G - in the genome.

How are humans are nearly identical genetically in coding sequences but have unique DNA fingerprints?
Small nucleotide polymorphisms is one way that you get unique genetic fingerprints. Small stretches of DNA that can be in the non-coding region and are just random differences in neutral coding errors. Google SNPS.
What has to happen in order to have a SNP?
A single-nucleotide polymorphism (SNP, pronounced snip) is a DNA sequence variation occurring when a singlenucleotide - A, T, C, or G - in the genome (or other shared sequence) differs between members of a species (or between paired chromosomes in an individual). For example, two sequenced DNA fragments from different individuals, AAGCCTA to AAGCTTA, contain a difference in a single nucleotide. In this case we say that there are two alleles : C and T. Almost all common SNPs have only two alleles.Within a population, SNPs can be assigned a minor allele frequency - the lowest allele frequency at a locus that is observed in a particular population. This is simply the lesser of the two allele frequencies for single-nucleotide polymorphisms. There are variations between human populations, so a SNP allele that is common in one geographical or ethnic group may be much rarer in another.
