in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
An animal breeding approach to the estimation of genetic and environmental trends from field populations.
Observed or phenotypic trends in animal performance can be readily quantified from information collected from research or field populations. Phenotypic performance is determined by the collective impact of systematic effects that vary by trait, but may include herd, year, sex, and age; additive genetic effects; and a remainder that is referred to as the lack-of-fit or unexplained residual. It i...
متن کاملGenetic engineering applications in animal breeding
This paper discusses the use of genetic engineering applications in animal breeding, including a description of the methods, their potential and current uses and ethical issues. Genetic engineering is the name of a group of techniques used to identify, replicate, modify and transfer the genetic material of cells, tissues or complete organisms. Important applications of genetic engineering in an...
متن کاملEstimation of the breeding value of morphophysiological traits of maize (Zea mays L.) genotypes using BLUP method
Knowledge of genes action on important traits and their breeding value is necessary to achieve high yielding cultivars in food crops. Molecular markers has eliminated the need for knowing the pedigree of genotypes for estimating Kiniship matrix required to estimate breeding values of taits of interest. In this research, 97 genotypes of maize were evaluated for 17 different agronomic triats usin...
