Meiosis – The Genetics of Reproduction Meiosis is a form of cell division that creates gametes. It is comprised of two divisions that in the end, the resulting cell will contain half the chromosomal number of the parent cell. Know the different stages here...Related...
Thus, it is essential to quantify PI according to its ultimate definition, that is, to measure any investment by a parent that enhances offspring fitness at the expense of the parent's expectation for additional offspring (Fig. 1)1,2,4,15. Second, the conflict is among genes, not traits...
Paternal diet can influence the phenotype of the next generation, yet, the dietary components inducing specific responses in the offspring are not identified. Here, we use the Nutritional Geometry Framework to determine the effects of pre-conception pate
Over the last decade, there has been a significant increase in average paternal age when the first child is conceived, either due to increased life expectancy, widespread use of contraception, late marriages and other factors. While the effect of maternal ageing on fertilization and reproduction is...

Theory predicts unified sex ratios for most organisms, yet biases may be engendered by selfish genetic elements such as endosymbionts that kill or feminize individuals with male genotypes. Although rare, feminization is established for Wolbachia-infected
More subtle degrees of sex distortion — as revealed in this study — are by definition less likely to draw attention, yet may exist more broadly than appreciated. Heredity Sex bias in Australian Eurema DJ Kemp et al 292 DATA ARCHIVING These data have instead been placed in the Dryad ...
Influenza during pregnancy can affect the health of offspring in later life, among which neurocognitive disorders are among the best described. Here, we investigate whether maternal influenza infection has adverse effects on immune responses in offspring
(larvae and juveniles). BRTs for purebred crosses were built using environmental covariates sourced from a single reef, i.e. crosses in which both parents were sourced from Curd reef incorporated environmental data from only Curd reef. Alternatively, hybrid crosses, by definition, have parents ...
