Combining Genetic and Ecological Data to Estimate Sea Turtle Origins
Many species of sea turtles spend part of their life cycle gathered in large feeding aggregations that combine individuals from widely separated rookery populations. Biologists have applied methods of mixed-stock analysis to mitochondrial DNA samples from rookeries and mixed populations to estimate the contributions of different rookeries to the mixed stock. These methods are limited by the amo...
متن کاملFeed Forward Artificial Neural Network Model to Estimate the TPH Removal Efficiency in Soil Washing Process
Background & Aims of the Study: A feed forward artificial neural network (FFANN) was developed to predict the efficiency of total petroleum hydrocarbon (TPH) removal from a contaminated soil, using soil washing process with Tween 80. The main objective of this study was to assess the performance of developed FFANN model for the estimation of TPH removal. Mater...
متن کاملConsiderations for Improving Feed Efficiency in Dairy Cattle
Intensive selection of sires is possible by using artificial insemination; coupled with accurate measurement of a potential sire’s genetic value, this has markedly improved genetics for easily measured traits like milk production and type traits. Increased milk production has in turn increased gross feed efficiency through dilution of maintenance. Additional genetic gains in feed efficiency wou...
متن کاملGenetic parameters for two selection criteria for feed efficiency in rabbits.
Improvement of feed efficiency can be achieved by genetic selection directly on feed to BW gain ratio or for alternative traits. In the present study, 2 different traits were explored in the growing rabbit and their heritability and genetic correlations with traits recorded between weaning (30 d) and 63 d of age: i) residual feed intake (RFI), to select animals having low ad libitum feed intake...
متن کاملEfficiency of anchored and non-anchored ISSR markers to estimate genetic diversity among bread wheat cultivars
DNA markers are integrally connected to the success of molecular breeding and are fundamentally required by breeders to be able to, a. identify new gene sources in the available biodiversity, b. select parents in order to increase heterosis, c. decrease the number of backcross generations for gene introgression breeding programs, and d. carry out marker-assisted selection (MAS). The present re...
