Term
Microsatellite
Definition
also known as Simple Sequence Repeats (SSRs) or sometimes called Short Tandem Repeats (STR) are repeating sequences of 1-6 base pairs of DNA. Used as markers
Term
genotype
Definition
is the genetic makeup of a cell, an organism, or an individual (i.e. the specific allele makeup of the individual) usually with reference to a specific character under consideration.
Term
Phenotype
Definition
is any observable characteristic or trait of an organism. Phenotype result from the expression of an organism's genes as well as the influence of environmental factors and the interactions between the two.
Term
point mutation
Definition
or single base substitution is a type of mutation that causes the replacement of a single base nucleotide with another nucleotide of the genetic material DNA or RNA
Term
Polymorphism
Definition
Differences in DNA sequence of a known organism
Term
RFLP
Definition
(Restriction Fragment Length polymorphism) is a technique that exploits variations in homologous DNA sequences. It refers to a difference between samples of homologous DNA molecules that come from differing locations of restriction enzyme sites.-They are broken into pieces by restriction enzymes and the resulting fragments are separated by lengths in gel electro.
Term
SNP
Definition
(Single Nucleotide Polymorphism) variation occurring when a single nucleotide differs between members of a species or paired chromosomes in an individual ex. AAGCCTA and AAGCTTA
Term
SSR
Definition
Simple Sequence Repeats, are repeating sequences of 1-6 base pairs of DNA
Term
VNTR
Definition
(Variable number tandem repeat) is a location in a genome where a short nucleotide sequence is organized as a tandem repeat. This is useful in DNA fingerprinting
