A Bayesian approach for constructing genetic maps when markers are miscoded
The advent of molecular markers has created opportunities for a better understanding of quantitative inheritance and for developing novel strategies for genetic improvement of agricultural species, using information on ...
Epidemiology and genetics of endemic goiter. II. Genetic aspects
Complex genetic models and segregation analysis were applied to family data obtained in a hyperendemic goiter area in Brazil. The single locus and Falconer's models did not fit the data. Edward's model showed convergency, ...
Use of progeny testing in beef cattle: Prediction of genetic gain in a Nelore Cattle Breeding Program
Genetic gains predicted for selection, based on both individual performance and progeny testing, were compared to provide information to be used in implementation of progeny testing for a Nelore cattle breeding program. ...
Environmental and genetic factors affecting the weaning-estrus interval in sows
We examined the effects of environmental and genetic factors on the weaning-to-estrus interval (WEI) in sows. In order to perform the analyses of the environmental factors, 8104 observations of the 1st to the 6th WEI were ...
Genetic principal components for reproductive and productive traits in dual-purpose buffaloes in Colombia
A multitrait model (MC) and 5 reducedrank models with principal component structure (components PC1, PC1:2, PC1:3, PC1:4, and PC1:5) were compared. The objectives were to determine the most appropriate model for estimating ...
Linear and Poisson models for genetic evaluation of tick resistance in cross-bred Hereford x Nellore cattle
Cattle resistance to ticks is measured by the number of ticks infesting the animal. The model used for the genetic analysis of cattle resistance to ticks frequently requires logarithmic transformation of the observations. ...
Conservation of Brycon orbignyanus natural populations and stocks for their reproductive, genetic, environmental sustainability: A model for species threatened with extinction

Genetic and phenotypic trends for growth traits of buffaloes in Brazil
(Pagepress Publ, 2007-01-01)
The objectives this paper were to estimate genetic parameters and genetic and phenotypic trends of birth weight (BWT) and weights adjusted to 205 (WT205), 365 (WT365) and 550 (P550) days of age of beef buffaloes born from ...
