studbook information collected from 1988 to 2011 in jafarabad breeding station of moghani sheep, north-west of iran, related to 9,457 lambs were used to study the genetic diversity and to evaluate the effectiveness of an implemented rotational mating scheme using pedigree analysis. lambs born during 2009-2011 were considered as reference population. means inbreeding and average coancestry for t...

in this research, two mating schemes for the management of recessive genetic disorders affecting abortion in a dairy cattle population were simulated. the first mating scheme was performed under three different scenarios: 1. the mating of a pair of two carriers of the same lethal haplotype was avoided. 2. it was avoided matings in which the service sires and cow's sire carried the same let...

A method to calculate joint gene frequencies, which are the probabilities that two neutral genes taken at random from a population have certain allelic states, is developed taking into account the effects of the mating system and the mutation scheme. We assume that the mutation rates are constant in the population and that the mating system does not depend on allelic states. Under either--the c...

in order to evaluate the effect of different mechanical treatments (application of sulphuric acid, boiling water and flooding) on seed dormancy breaking of licorice, an experiment was carried out in randomized complete block design in 2012. moreover, a factorial scheme in rcbd was performed to assess the application of giberalic acid and potassium nitrate treatment as well as stratification and...
