Mothers can influence offspring’s height, lifespan and disease risk
The study, published today in Nature Genetics, found that genetic variants in the DNA of mitochondria could increase the risk of developing these conditions, as well influencing characteristics such
Advantages and disadvantages of asexual reproduction in plants
Asexual reproduction in the plants The asexual reproduction is the production of new plants without using of seeds, it can incorporate new characteristics into the plants, it is easier and cheaper, it can produce...
Fertility Treatments Don't Raise Cancer Risk for Offspring
WEDNESDAY, Feb. 6, 2019 (HealthDay News) -- All expectant parents worry, and for those undergoing fertility treatments, there are additional concerns about the health of their child. But a new study finds one less thing they need to stress over -- their children don't appear to be at greater risk o...
Perceived Predation Risk Reduces the Number of Offspring Songbirds Produce per Year
Predator effects on prey demography have traditionally been ascribed solely to direct killing in studies of population ecology and wildlife management. Predators also affect the prey’s perception of predation risk, but this has not been thought to meaningfully affect prey demography. We isolated the effects of perceived predation risk in a free-living population of song sparrows by actively eliminating direct predation and used playbacks of predator calls and sounds to manipulate perceived risk. We found that the perception of predation risk alone reduced the number of offspring produced per year by 40%. Our results suggest that the perception of predation risk is itself powerful enough to affect wildlife population dynamics, and should thus be given greater consideration in vertebrate conservation and management.
Children born by assisted reproduction have higher Asthma risk
A new study has found that-Children conceived by assisted reproductive technologies have higher Asthma risk. The result of the study showed an elevated risk of asthma among ART offsprings in...
If you could clone yourself, would you still have sex?
Imagine how easy life would be if you could produce offspring without a mate. Sexual reproduction is the most common mating system in the animal kingdom. But in many species, females do not require males…
Occupational and environmental risks to reproduction in females: Specific exposures and impact - UpToDate
There has been growing awareness of the prevalence of chemical and metal exposures to pregnant women. At the same time, there has been increasing concerns about
Maternal Immune Activation and Related Factors in the Risk of Offspring Psychiatric Disorders
Maternal immune activation (MIA) at the time of gestation has been linked to increased risk of neurodevelopmental psychiatric disorders. Animal and human models have been used to evaluate the relationship between MIA and these outcomes. Given that each of these two disciplines of study have their benefits and limitations, a translational perspective is expected to illuminate more than by the use of any single approach. In this article, we discuss this translational framework and explore how it may be enhanced by the utilization of epigenetic studies and by investigating the microbiome. In this perspectives piece, we focus on the impact of epidemiologic studies, animal models, and preclinical studies in the literature on MIA as well as the potential for greater integration between fields.
Plants: An Introduction to Vegetative Reproduction | Biology article by D G Mackean
Biology article by D G Mackean introducing vegetative reproduction in plants, covering bulbs, corms, rhizomes, runners, grafting, cuttings, and tissue culture, accompanied by detailed biological drawings
Probably the most dramatic part of the reproduction process is the time when the hatchlings run for their lives from the nest to the ocean. A path that is full
