How Do You Explain Heritability?
A More Accurate, but Simplified, Definition Is This: Heritability Is the Proportion of This Total Variation Between Individuals in a Given Population Due to...

Also to know is, what is meant by heritability?
Heritability is a statistic used in the fields of breeding and genetics that estimates the degree of variation in a phenotypic trait in a population that is due to genetic variation between individuals in that population.
Subsequently, question is, how does heritability work? Heritability is the extent to which differences in the appearance of a trait across several people can be accounted for by differences in their genes. Heritability does not reflect the extent to which traits are passed down from parent to offspring. Heritability estimates are usually generated by twin studies.
Similarly, how do you interpret heritability?
Because heritability is a proportion, its numerical value will range from 0.0 (genes do not contribute at all to phenotypic individual differences) to 1.0 (genes are the only reason for individual differences). For human behavior, almost all estimates of heritability are in the moderate range of . 30 to . 60.
What is the heritability index and why is it important?
In other words, the heritability index tells you how much you could improve the accuracy of a prediction about one identical twin, given a measurement of the same variable obtained from the other identical twin, as compared to typical fraternal twins measured for the same trait.
