Optimum family size in progeny testing and the theory of games
In this paper, the optimum family size in a progeny test with limited testing facilities was determined for a scheme where several commercial companies were competing. Companies which determined family size in order to maximize the expected proportion of sires that will be selected from its stock were considered as competitive. On the other hand, companies that determined family size in order t...

متن کاملdetermination of optimum size for rice farms in guilan province
abstract the production unit size is one of the effective factors in optimum uses of inputs. since optimum size is affected by the characters and economical conditions in each district, the studies for determining the optimum farm size should be done specially for each crop and each district. in this study tried to determine the optimum rice farm size in guilan province which is one of the most...
متن کاملChromosome C-banding in Mus musculus L.1766 Strains Shows a Fixed Position for the Centromere and Variable Amounts in Different Populations
Three subspecies of Mus musculus have been recognized in Iran so far. The house mouse (genus0T 0T2TMus2T, species0T 0T2TMus musculus2T) are recognized for their highly conserved morphology and chromosomal structure, but some chromosomal characters offer accurate taxonomic markers in this species that has been shown any unambiguous diagnostic morphological traits. Among the chromosomal character...
