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.
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.
