gen.gc: Genetic contribution of ancestors

Description

Returns the genetic contribution of ancestors to the gene pool of sepcifiec probands

Usage

gen.gc(gen, pro=0, ancestors=0, vctProb=c(0.5,0.5,0.5,0.5), typeCG="IND")

Value

A matrix with rows corresponding to probands and columns corrsponding to ancestors when typeCG="IND". For the other typeCG values, rows are ancestors and there is one column containing mean, product, total or cumulative values.
