Abstract

Bi-directional polymerase chain reaction (PCR) amplification of specific alleles (Bi-PASA). Two outer primers (P and Q) and two inner primers (A and B) are used. A and B are each specific for different alleles. In heterozygotes, three segments are amplified: a segment of size AQ resulting from one allele, another segment of size PB resulting from the second allele, and a combined segment of size PQ. In homozygotes, segment PQ and either segments AQ or PB amplify.
