| What if the heritabilities observed for IQ are a result of indirect effects that can be changed by changing social practice? |
|
| In the Dutch study, more than 70 per cent of cows studied had at least one claw disorder, and researchers found heritabilities up to 10 per cent. |
|
| There certainly remains a need for more accurate methods to estimate heritabilities and genetic correlations in the absence of pedigree information. |
|
| They suffer from low heritabilities and a corresponding lack of genetic gain in conventional selection and breeding programmes. |
|
| This tends to make it more difficult to have reliable data and contributes to low heritabilities. |
|
| Maybe the reason for low heritabilities is that we haven't defined or identified these traits accurately. |
|
| Because reproductive traits have low heritabilities, we need more information than with production traits. |
|
| However, other studies have found medium heritabilities for dystocia, metritis, milk fever and mastitis. |
|
| These values are comparable to the heritabilities of some physiological performances in domestic animals, such as lifetime egg or milk production. |
|
| In addition, the higher heritabilities of the calving performance traits helps improve the accuracy of the genetic evaluations for the correlated measures of female fertility. |
|
| More recently, proofs released in January 2010 experienced increased change following the implementation of updated estimates of heritabilities and genetic correlations across each of the first three lactations. |
|
| Genetic variation for disease incidence does exist, is economically important and justifies including disease in breeding programs, in spite of low heritabilities for disease traits. |
|
| Age adjustment factors, heritabilities and genetic correlations for scrotal circumference and related growth traits in Hereford and Brangus bulls. |
|
| Heritabilities are low, ranging from 3.5 to 8.5 per cent, and environmental factors obviously affect these disorders greatly. |
