Use of different genetic markers in studies on avian introgression in three time periods (1987-2000, 2001-2010, and 2011-2017). From 2001 onwards, genomic techniques are being applied. Traditional markers, such as microsatellites and mtDNA, remain popular
The D-statistic considers ancestral ('A') and derived ('B') alleles across the genomes of four taxa. Under the scenario of incomplete lineage sorting without gene flow, two particular allelic patterns 'ABBA' and 'BABA' should occur equally frequent. An excess of either ABBA or BABA, resulting in a D-statistic that is significantly different from zero, is indicative of gene flow between two taxa. The table below shows the range of D-statistics for different bird taxa
