Description Usage Arguments Value Note Author(s) Examples

This function calculates the Mean of Transformed Kinships (MTK) of a set of genotypes.

`genos` |
A matrix of genotypes, where each column is one individual, each row is one marker, and marker values are 1, 0, or -1, or NA, where 0 represents a heterozygous marker, and NA represents missing data. Note that this coding is different from the earlier MtkCalc, which cannot handle heterozygous markers. All data in this matrix must be numeric. |

`subset` |
A vector of genotype names for which to calculate MTK. |

`mat` |
A kinship matrix, if one has already been computed for the population. |

`power` |
The transformation that should be made to the kinship matrix, if the MTK criterion is used. If power=1, the kinship matrix is not transformed, if power=2, the kinship matrix is squared, etc. When the power is higher, this function preferentially eliminates genotypes that are closely related to other genotypes in the population. |

The MTK of the specified subset.

The ability to recognize heterozygous markers was included in MTK, resulting in a slightly different genotype coding scheme than the earlier MtkCalc.
