Jacquard's condensed identity coefficients

Jacquard coefficient	Probability that for individuals i and j
Δ₁	i₁ = i₂ = j₁ = j₂
Δ₂	i₁ = i₂ ≠ j₁ = j₂
Δ₃	i₁ = i₂ = j₁ ≠ j₂ or i₁ = i₂ = j₂ ≠ j₁
Δ₄	j₂ ≠ i₁ = i₂ ≠ j₁ and j₁ ≠ j₂
Δ₅	i₁ ≠ i₂ = j₁ = j₂ or i₂ ≠ i₁ = j₁ = j₂
Δ₆	i₂ ≠ j₁ = j₂ ≠ i₁ and i₁ ≠ i₂
Δ₇	i₁ = j₁ ≠ i₂ = j₂ or i₁ = j₂ ≠ j₁ = i₂
Δ₈	Identity is shared between i and j through only one pair of alleles
Δ₉	No identity is shared between any alleles of i and j
