Mountain gorillas, who live in close-knit social groups with siblings and non-siblings of both sexes throughout their lives, show distinct behavioral biases towards maternal versus paternal kin.

Genomic imprinting in the bryophyte Marchantia polymorpha by Polycomb results in maternal dominance of embryonic gene expression.

Epigenomic and transcriptomic analysis reveals that paternal obesity influences sperm histone H3 lysine 4 tri-methylation enrichment and placenta gene expression, which in turn negatively impact its development and function in a manner that may contribute to metabolic disease in offspring.

The uniparental inheritance of mammalian mitochondria results from elimination of paternal mitochondria by a mitophagic process that requires the E3 ubiquitin ligases PARKIN and MUL1.

Predisposition to obesity-associated diseases is dependent on the ancestors' diet.

Analysis of a spermiogenesis protein reveals a new chromatin requirement for synchrony between maternal DNA packaged in the egg and sperm-packaged paternal DNA in the first embryonic mitosis in Drosophila melanogaster.

Limiting cytoplasmic streaming contributes to maintaining spatial separation of the sperm contents from the female meiotic spindle after fertilization.

Mandrill mothers know best because they use their offspring’s facial resemblance with other infants to guide their social opportunities towards similar-looking ones as an adaptive maternal behavior.

A novel paternal effect based on nicotine exposure reveals that offspring exhibit an adaptive, yet nonspecific, resistance to multiple toxins.
