ABSTRACT Evolutionary transitions from oviparity to viviparity are frequent across diverse taxa. Some species also display intraspecific variation in parity mode, or they exhibit an intermediate mode by laying eggs containing embryos at variable, often advanced stages of development. How such natural quantitative variation in egg retention...

Evolutionary transitions from egg laying (oviparity) to live birth (viviparity) are common across various taxa. Many species also exhibit genetic variation in egg-laying mode or display an intermediate mode with laid eggs containing embryos at various stages of development. Understanding the mechanistic basis and fitness consequences of such...

Most eukaryotes inherit their mitochondria from only one of their parents. When there are different sexes, it is almost always the maternal mitochondria that are transmitted. Indeed, maternal uniparental inheritance has been reported for the brown alga Ectocarpus but we show in this study that different strains of Ectocarpus can exhibit...
