What is the correct formula for calculating heritability?
A) 2 (rMZ - rDZ)
B) 2 - (rMZ - rDZ)
C) 2 + (rMZ - rDZ)
D) 2 (rDZ - rMZ)

Question

Quizplus · Accepted Answer

The correct formula for calculating heritability is 2 (rMZ - rDZ), where rMZ is the correlation coefficient between monozygotic twins and rDZ is the correlation coefficient between dizygotic twins. This formula takes into account the fact that monozygotic twins share 100% of their genetic material while dizygotic twins share 50%, allowing for a more accurate estimate of the contribution of genetics to a particular trait or characteristic.
