How are microsatellites used in population genetics?

How are microsatellites used in population genetics?

Microsatellite markers are inherited from both parents, making them useful for parentage analysis (think paternity testing) and population genetic studies. If a microsatellite locus is polymorphic, it means that there is more than one potential allele at a single locus (a specific marker site).

What is a genetic microsatellite marker?

​Microsatellite Microsatellite sequences are repetitive DNA sequences usually several base pairs in length. Microsatellite sequences are composed of non-coding DNA and are not parts of genes. They are used as genetic markers to follow the inheritance of genes in families.

Can microsatellites be genetically mapped?

Genetic maps play an important role in gene mapping. For identical numbers of meioses and intermarker distances, genetic maps constructed from microsatellite markers will be more precise than maps assembled from SNP markers, due to the higher levels of heterozygosity for microsatellite markers.

Why are microsatellites used in DNA profiling?

Microsatellites are the most widely applied molecular markers in population genetic studies, conservation genetics, and paternity tests because the markers are codominant, highly reproducible, and can be obtained by the PCR once primers can be developed (Ellegren 2004).

What are SSRs in genetics?

5.2. Simple sequence repeats (SSRs) or microsatellites are DNA stretches consisting of short, tandemly repeated di-, tri-, tetra-or penta-nucleotide motifs. Simple sequence repeats have been found in all eukaryotic species that were scrutinized for them (Tautz and Renz, 1984).

What are SSR primers?

Simple sequence repeats (SSRs) or microsatellites are DNA stretches consisting of short, tandemly repeated di-, tri-, tetra-or penta-nucleotide motifs. To amplify SSRs by PCR, information on unique flanking DNA sequences is required for primer design.

What is minisatellite and microsatellite?

Minisatellite is a section of highly repeated DNA that consists of a series of a repeating sequence composed of 10 to 100 base pairs. Microsatellite is a section of repetitive DNA that consists of short repeating sequences composed of 1 to 9 base pairs.

What is microsatellite DNA sequence?

Microsatellite Microsatellite sequences are repetitive DNA sequences usually several base pairs in length. Microsatellite sequences are composed of non-coding DNA and are not parts of genes. They are used as genetic markers to follow the inheritance of genes in families.

What are microsatellites and why are they important?

Microsatellites are short, repeated units of DNA that occur in many places in the genome. They are typically quite variable among individuals, making them an appropriate marker for studying population genetics questions.

Can microsatellites be used as genetic markers for paternity testing?

The increasing availability of DNA amplification by PCR at the beginning of the 1990s triggered a large number of studies using the amplification of microsatellites as genetic markers for forensic medicine, for paternity testing, and for positional cloning to find the gene underlying a trait or disease.

Are microsatellite markers a useful tool in studying Grapevine genetics?

Although microsatellite markers are a robust and useful tool in studying grapevine genetics, their development is time-consuming and expensive (prior to the draft grapevine genome sequence being released).
