Question

This is a Narrow sense heritability Problem:

1) If the correlation coefficient of total body mass between full siblings is 0.20, then what is the narrow sense heritability?

Write an interpretation of this heritability value, using the most accurate language possible:

2) If the correlation coefficient of total white blood cell count between monozygotic twins is 0.78, then what is the narrow sense heritability?

Write an interpretation of this heritability value, using the most accurate language possible:

Explanation / Answer

Narrow sense of heritability (h2) is the rate of trait variation because of additive genetic factor. There is range to determine the narrow sense rate. For example 0.5 to 0.8

This is also known as additive model for example parent and offspring correlation found around .10 so the narrow sense range will defined as 2* .10 = 20%. It could not more than 100%. Suppose narrow range of cousins is 0.15* 8 = 120%
