Polymerase chain reaction (PCR)
Biology; Genetics
A method for exponentially increasing the number of copies of a specific DNA sequence. The use of PCR enables the genetic analysis of biological samples containing only tiny amounts of DNA
Polymorphism
Biology; Genetics
Variation in a region of DNA sequence among different individuals; the variation should be present in at least 1-2% of the population to be considered a polymorphism.
Positive predictive value (PPV)
Biology; Genetics
The probability of an individual having a particular disorder following a positive test, i.e. the proportion of true positive results relative to the total number of positive tests. As the prevalence ...
Preimplantation genetic diagnosis
Biology; Genetics
se of genetic testing on one or two cells taken from a live early-stage embryo created by in vitro fertilisation. The procedure is usually carried out in order to determine whether the embryo is ...
