Coefficient of parentage

...The coefficient of parentage between individuals I and J is the correlation coefficient between genotype values ​​when the effects of genes are assumed to be additive (dominance relationship, no interaction), and is given by the following formula. Here, F I and F J are the inbreeding coefficients of I and J, respectively, and F IJ is the parentage coefficient between I and J. The parentage coefficient is also a coefficient that indicates how similar individuals are genetically, and indicates the probability that when one gene is taken from I and one from J at a certain locus, they are derived from a common ancestral gene, and is calculated by the following formula. ...

*Some of the terminology explanations that mention "coefficient of parentage" are listed below.

…個体Iと個体Jの間の血縁係数は,遺伝子の作用が相加的(優性関係,相互作用がない)であると仮定したときの遺伝子型値間の相関係数であり,次式で与えられる。ここにFI,FJはそれぞれI,Jの近交係数であり,FIJはIとJの間の近縁係数である。近縁係数coefficient of parentageも個体が遺伝的にどれほど似ているかを示す係数で,ある遺伝子座でIから1個,Jから1個の遺伝子を取り出したとき,それらが共通の祖先遺伝子から由来する確率を示すもので,次式で計算される。…
