When reared with predators, the offspring of both populations demonstrated similar predator-induced phenotypic plasticity (although significant, the population by treatment interaction explained comparatively little variation).
Unfortunately, we could not verify the non-random association between the transgenic trait and other phenotypic traits in the offspring of weedy populations because of the very low rate of transgene introgression.
Recent studies indicate that persistent organohalogen pollutants (POPs) may contribute to sex ratio changes in offspring of exposed populations.
We compared the genotoxic effects of a carcinogenic PAH, BaP, in offspring of two populations of Atlantic killifish: one from a reference site and one from an area along the ER that is highly contaminated with PAHs.
To evaluate the impact of assisted reproductive technology (ART) on the offspring of Chinese population.
The Mozambique tilapias were F1 offspring of wild population coming from South Africa, and the red tilapias were from a local red tilapia strain in Malaysia and Singapore, which originated from a hybrid between Mozambique tilapia and Nile tilapia.
All wild-caught individuals from population 09-032 that we examined lacked a columellar band and some had axial ribs (Table 2), but the band was faintly present on lab-bred F1 offspring of the population, which lacked axial sculpture, even on juvenile whorls.
Because we collected the offspring of the mapping populations during their early growth stages, the sex of the offspring could not be identified.
It was able to generate hybrid vigor for offspring of crosses between populations that had been allowed to diverge for several generations, and it also displayed a dramatic fall in fitness as the genetic distance between parents increased to the point of preventing the formation of viable offspring.
Developmental plasticity allows for the production of phenotypically diverse offspring in populations of genetically identical individuals, which increases the probability of survival in changing and challenging environments.
