Genes

• A genotype is the genetic makeup of an organism and can refer to the two alleles inherited for a gene or segment of DNA.
• A microsatellite is a highly variable region of DNA in which a set of nucleotide sequences two to five base pairs long is repeated multiple times. (These are also referred to as short tandem repeats, STRs.)
• The specific location of a DNA sequence on a chromosome is called a DNA locus
• One of two or more alternative forms (based on nucleotide sequence) for a DNA region found at the same chromosomal locus is called an allele
• Allele Frequency refers to the relative frequency of a gene variant at a locus in a population.
• PCR is a technique used to make billions of copies of a specific DNA sequence.
• PCR definition is Polymerase Chain Reaction
• Gel electrophoresis is a technique used to separate DNA fragments based on size.
