random regression models (rrm) are used for genetic estimations of milk traits in dairy cows. rrm utilize data on traits that are repeated during the time, such as milk trait, which allows of the evaluation of the test day production information. in this study, to estimate genetic parameters for milk production trait, test day records (tdr) were collected from the first lactation of holstein co...
a total of 2000 records of egg quality of 746 birds and body weight data from 17th generation of fars native fowl breeding station were used to estimate the genetic parameters of egg quality and body weight traits. six univariate animal models with different random effects were fitted for each trait. a model with direct additive genetic and maternal permanent environmental effects was the most ...
For genetic analyses of growth traits of Kermani sheep including body weight at birth, three, six, nine and twelvemonths of age, 10, 459 body weight records measuredon 3132 animals originated from 78 sires and 1163 dams were used. The data were collected at Kermani sheep breeding station during 1988 to 2010. The data were analyzed using a multivariate animal model. In the model, animal age, sex...
Disorders of sex development (DSDs) are a group of genetic abnormalities which develop from different conditions including chromosomal and gonadal disorders. The careful study of underlying pathways of sex development is necessary due to identification of genes that have a role in these pathways. And it can help to better understanding of the cause of disorder, genetic counseling and prevention...
