Use this feature to specify whether to use numeric additive coding or dominant coding when converting to expanded genotypes .
To convert genotypes to values representing whether or nor a specific allele is present in one or two copies.For example, if Marker1 has three alleles ( A , B , and C ) three columns ( Marker1_A , Marker1_B , and Marker1_C ) are generated. In column Marker1_A , individuals with two copies of A at Marker1 ( A/A homozygotes) are denoted with a “2”. Individuals with one copy of A ( A/B and A/C heterozygotes) are denoted with a “1”. Individuals with no copies of A ( B/B and C/C homozygotes and B/C heterozygotes) are denoted with a “0”. The Marker1_B and Marker1_C columns are coded for alleles B and C in a similar fashion. For example, if Marker1 has three alleles ( A , B , and C ) three columns ( Marker1_A , Marker1_B , and Marker1_C ) are generated. In column Marker1_A , individuals with at least one copy of A at Marker1 ( A/A homozygotes or A/B or A/C heterozygotes) are denoted with a “1”. Individuals with no copies of A ( B/B and C/C homozygotes and B/C heterozygotes) are denoted with a “0”. The Marker1_B and Marker1_C columns are coded for alleles B and C in a similar fashion.
