Maternal effects on offspring depend on female mating pattern and offspring environment in yellow dung flies.
Direct costs and benefits to females of multiple mating have been shown to have large effects on female fecundity and longevity in several species. However, with the exception of studies examining genetic benefits of polyandry, little attention has been paid to the possible effects on offspring of multiple mating by females. We propose that nongenetic effects of maternal matings on offspring fi...
متن کاملEffects of maternal and offspring environmental conditions on growth, development and diapause in latitudinal yellow dung fly populations
Extensive phenotypic plasticity can allow populations to persist in changing environments. Maternal effects represent one important but often neglected source of phenotypic plasticity. Mothers and offspring of 2 high(northern Norway and central Sweden) and 2 low(northern and southern Spain) latitude yellow dung fly Scathophaga stercoraria (Diptera: Scathophagidae) populations were exposed to co...
متن کاملEffect of maternal diabetes on female offspring
OBJECTIVE To evaluate the effect of maternal diabetes on the blood pressure and kidney function of female offspring, as well as if such changes exacerbate during pregnancy. METHODS Diabetes mellitus was induced in female rats with the administration of streptozotocin in a single dose, one week before mating. During pregnancy, blood pressure was measured through plethysmography. On the 20th da...
متن کاملStereological Study on the Effects of Maternal Caffeine Consumption on Histomorphometric Changes of Testis and Prostate in Rat Offspring
Background and Objective: It is conceivable that caffeine consumption would induce gonadal changes. The aim of this study is to assess the impact of embryonic caffeine exposure on rat testis and prostate. Materials and Methods: Female rats were divided into (n=7): A control, only received drinking water. B and C groups received caffeine low dose (26 mg/kg) and high dose (45 mg/kg) respectively...
متن کاملP-53: Maternal Diet, Vaginal pH and Time of Ovulation Effects on Offspring`s Sex Ratio
Background Although there are different ways to achieve the desired sex of the fetus, most of those are not completely effective. This paper reports a study on human to check the theories which hypothesize that high potassium maternal diet, douching with alkaline substance to change vaginal PH and intercourse around ovulation affects the sex ratio of the progeny MaterialsAndMethods A quasi-expe...
