- Minisatellites Are Useful For Genetic Mapping
KEY TERMS:Microsatellite DNAs consist of repetitions of extremely short (typically <10 bp) units. Minisatellite DNAs consist of ~10 copies of a short repeating sequence. the length of the repeating unit is measured in 10s of base pairs. The number...
- Rflps And Snps Can Be Used For Genetic Mapping
KEY TERMS:The haplotype is the particular combination of alleles in a defined region of some chromosome, in effect the genotype in miniature. Originally used to described combinations of MHC alleles, it now may be used to describe particular combinations...
- A Locus May Have More Than One Wild-type Allele
KEY TERMS:Polymorphism (more fully genetic polymorphism) refers to the simultaneous occurrence in the population of genomes showing variations at a given position. The original definition applied to alleles producing different phenotypes. Now it is also...
- A Locus May Have Many Different Mutant Alleles
KEY TERMS:A locus is said to have multiple alleles when more than two allelic forms have been found. Each allele may cause a different phenotype. KEY CONCEPTS: The existence of multiple alleles allows heterozygotes to occur representing any pairwise...

polymorphism
Term: polymorphism
Literally meaning: ?having multiple forms"
Origin: Anc Greek
????-/poly-(=many, several)
+ ?????/morphe(=shape, form)
Coined/History
The first polymorphism was recorded in 1900 by Landsteiner and it was the ABO blood group polymorphisms.
Definition
(genetics) Polymorphisms are differences in nucleotide sequence at the same locus among individuals without obvious pathological effect.
(biology) Polymorphism are genetic variations in a paricular species which express different phenotypes (subtypes).
