Polymorphisms
A polymorphism is a genetic variant that appears in at least 1% of a population.
Examples: ...
Genetic polymorphisms are genetic variations in genes, e.g., single nucleotide polymorphisms (SNP).
Subcategories
This category has only the following subcategory.
Single nucleotide polymorphisms (SNPs) are a type of polymorphism involving variation of a single base pair.
Polymorphisms. Variant forms of a particular gene that occur simultaneously in a population.
Polynucleotide. A DNA polymer composed of multiple nucleotides. (See Nucleotide.) ...
STR Polymorphisms
Most of our DNA is identical to DNA of others. However, there are inherited regions of our DNA that can vary from person to person. Variations in DNA sequence between individuals are termed "polymorphisms".
Many polymorphisms-small regions of DNA that vary among individuals-also were identified during the HGP, mostly single nucleotide polymorphisms (SNPs).

A technique for detecting polymorphisms at a particular locus. Following PCR amplification of a locus, polymorphisms are detected by differences in restriction fragment sizes between individuals.

SSLP Simple Sequence Length Polymorphisms (SSLPs) are markers that detect differences in the length of a PCR product.
Restriction fragment length polymorphisms (RFLP) are variation in DNA fragment banding patterns of electrophoresed restriction digests of DNA from different individuals of a species.
To 'genotype' (verb) is to example polymorphisms (e.g. RFLPs, microsatellites, SNPs) present in a sample of DNA. You might be looking for linkage between a microsatellite marker and an unknown disease gene.
restriction fragment length polymorphisms (RFLPs)
Differences in DNA sequence on homologous chromosomes that result in different patterns of restriction fragment lengths (DNA segments resulting from treatment with restriction enzymes); ...
A technique in which DNA restriction fragment length polymorphisms (RFLPs) are used as reference markers for mapping in relation to known genes or other RFLP loci.

The markers where hybridization occurred are referred to as RFLPs (restriction-fragment-length polymorphisms). The longer fragment in sickle-cell individuals is interpreted as evidence of a mutation in the recognition sequence.
DNA fingerprinting A process by which an individual can be uniquely identified (well, narrowed down substantially!) by testing for multiple DNA polymorphisms.
Polymorphism: Difference in DNA sequence among individuals. Genetic variations occurring in more than 1% of a population would be considered useful polymorphisms for genetic linkage analysis. Compare mutation.
