| 31. | A prerequisite for heritability analyses is that there is some population variation to account for.
|
| 32. | In practice, all human behavioral traits vary and almost all traits show some heritability.
|
| 33. | For example, Peter Schonemann has criticized methods for estimating heritability developed in the 1970s.
|
| 34. | Throat color in side-blotched lizards is genetically determined, and has high heritability.
|
| 35. | For this population, at least, possible explanations for this atypical heritability pattern exist.
|
| 36. | Rangeland assessments show that the heritability of aggressiveness in cattle is around 0.36.
|
| 37. | According to Gould, Jensen uses heritability to measure differences " between " populations.
|
| 38. | Estimates of heritability use statistical analyses to help to identify the causes of differences between individuals.
|
| 39. | Heritability estimates reflect the amount of variation in genotypic effects compared to variation in environmental effects.
|
| 40. | An example structural model ( for the heritability of height among Danish males ) is shown:
