Genotype Recoding

Select:	When:
Numeric Additive (2 1 0)	To convert genotypes to values representing the count of minor alleles. Regardless of the actual identifier, individuals homozygous for the most common allele are identified with a "0". Heterozygotes for the most common allele and another, less common allele, are identified a "1". All of the less common alleles, regardless of the number of different alleles, are grouped together. All individuals without the most common allele, including both homozygotes for less common alleles and their heterozygotes, are identified with a "2". Individuals are scored for each locus, in one column, in the same way.
Numeric Dominant (1 1 0)	To convert genotypes to values indicating a dominant model for the minor allele(s). Regardless of the actual identifier, individuals homozygous for the most common (major) allele are identified with a "0". All of the other alleles, regardless of the number of different alleles, are grouped together. All individuals not containing the most common allele, whether homozygous or heterozygous, are identified with a “1”. Individuals are scored for each locus, in one column, in the same way.
Numeric Heterozygous (0 1 0)	To convert genotypes to values indicating if they are heterozygous for the major allele. Regardless of the actual identifier, individuals heterozygous for the major allele (that is, they have exactly 1 copy) are identified with a "1". All other genotypes are coded as a "0". Individuals are scored for each locus, in one column, in the same way.
Numeric Recessive (1 0 0)	To convert genotypes to values indicating a recessive model for the minor allele(s). Individuals containing the most common (major) allele, whether homozygous or heterozygous, are identified with a "0". All of the other alleles, regardless of the number of different alleles, are grouped together. All individuals without the major allele, whether homozygous or heterozygous, are identified with a "1". Individuals are scored for each locus, in one column, in the same way.
Genotype string (A/A, A/B, B/B)	To convert alleles or genotypes (numerically coded or single character). Regardless of the values initially used, alleles are converted to “A/A” for genotypes homozygous or heterozygous for the minor allele(s), “A/B” for heterozygotes containing one copy of the major allele, and “B/B” for genotypes homozygous for the major allele. Genotypes are converted as follows: 2 or "A" is converted to "A/A", 1 or "H" is converted to "A/B", and 0 or "B" is converted to "B/B".

To convert genotypes to values representing the count of minor alleles.

Individuals are scored for each locus, in one column, in the same way.

Numeric Dominant (1 1 0)

To convert genotypes to values indicating a dominant model for the minor allele(s).

Regardless of the actual identifier, individuals homozygous for the most common (major) allele are identified with a "0". All of the other alleles, regardless of the number of different alleles, are grouped together. All individuals not containing the most common allele, whether homozygous or heterozygous, are identified with a “1”.

Individuals are scored for each locus, in one column, in the same way.

Numeric Heterozygous (0 1 0)

To convert genotypes to values indicating if they are heterozygous for the major allele.

Regardless of the actual identifier, individuals heterozygous for the major allele (that is, they have exactly 1 copy) are identified with a "1". All other genotypes are coded as a "0".

Individuals are scored for each locus, in one column, in the same way.

Genotype string (A/A, A/B, B/B)

To convert alleles or genotypes (numerically coded or single character).

Regardless of the values initially used, alleles are converted to “A/A” for genotypes homozygous or heterozygous for the minor allele(s), “A/B” for heterozygotes containing one copy of the major allele, and “B/B” for genotypes homozygous for the major allele. Genotypes are converted as follows: 2 or "A" is converted to "A/A", 1 or "H" is converted to "A/B", and 0 or "B" is converted to "B/B".
