Computes F statistics according to Weir and Cockerham's estimators. Missing values are allowed and accounting for in the computation of Fst. The presence of missing values involves a downward bias in the computation of Fis. This function should not be used on haploid data.

`npop` |
total number of popluation present in the dataset |

`pop.mbrship` |
Vector of integers giving the population membership for each individual |

`ploidy` |
Integer: 1 or 2 (default is 2) under development. Do not use for haploid data. |

A list with components

`Fis ` |

`Fst ` |
A matrix of estimations the pairwise population Fst. (Only the upper triangular part is returned). |
