The effect of ordinary and restricted selection indices on body weight at different ages changes in birth weight of Iranian Moghani sheep was studied. Traits in the aggregate genotype were birth weight (BW), body weights at 3 (BW3) and 12 months of age (BW12). Two ordinary selection indices (I1 and I2) and two restricted selection indices (R1 and R2) were constructed. BW and BW3 were included i...

In this short retrospective study, the author gives account of some aspects and the main results of human population genetical studies in Hungary. In the foreground of his interest is research taking as its basis the population as a genetic unit, which demonstrates the genetic structures of the populations, the geographic (and other) mechanisms of isolation, migration, the variability of geneti...

Electrophoretic analyses of population genetic structure, both in the laboratory and in the field, have documented significant shifts in allozyme genotype frequencies in a variety of aquatic taxa as a result of environmental impacts. Studies are documented which indicate that contaminants may select for individuals with tolerant allozyme genotypes, causing the potential loss of individuals with...

We present a model for evolving population which maintains genetic polymorphism. By introducing random mutation in the model population at a constant rate, we observe that the population does not become extinct but survives, keeping diversity in the gene pool under abrupt environmental changes. The model provides reasonable estimates for the proportions of polymorphic and heterozygous loci and ...

the dry bubble disease, caused by lecanicillium fungicola, is an important fungal disease of white button mushroom in iranian mushroom production farms. twenty-three isolates of the pathogen collected in iran and identified as l. fungicola var. fungicola, were compared for genetic polymorphism, diversity in growth rate and virulence. ten universal rice primers (urp) were used to evaluate the ge...

malaysian mahseer, tor douronensis, locally known as “kelah” in peninsular malaysia or semah in sarawak is one of the important mahseers used for food as well as the aquarium industry and game fishing. this species is endemic to malaysian borneo river basins. the wild stocks of t. douronensis have declined substantially in recent years, due to over exploitation, pollution and illegal fishing pr...
