Mothers can non-genetically influence offspring phenotype in response to environmental conditions, including mate attractiveness. If such 'maternal effects' influence the offspring's reproduction and F2 generation, there is a mechanism for non-genetic trans-generational effects on phenotype, including epigenetic phenomena, with implications for evolution and population dynamics. We demonstrate ...
To determine the genetic basis of the resistance of Schistosoma mansoni to praziquantel (PZQ) and to understand whether the resistance is dominant or recessive trait, a schistosome cross was undertaken between a PZQ-susceptible and a PZQ-resistant isolate using infections of the single-sex cercariae which were identified by a direct W1-specific PCR technique. The resistances of F1 and F2 genera...
مطالعه اثر گروه ژنتیکی بر صفات رفتاری و تولیدی و برآورد میزان هتروزیس برای وزن لاشه در بلدرچین ژاپنی
In this study, male and female birds of two strains including pure white (P1) and pure wild (P2) were chosen as parental generation and were crossed reciprocally to create the F1 progeny. The F1 birds were mated randomly to produce the F2 progeny. The studied traits were body weight at different ages, slaughter weight, carcass weight, carcass composition, internal organs, tonic immobility (TI) ...
