Background and Aims Polyploidy is arguably the single most important genetic mechanism in plant speciation and diversification. It has been repeatedly suggested that polyploids show higher vegetative ...

The life history of Yucca glauca in the Great Plains was the subject of a four year field study. Data were incorporated in a stage transition model (based on rosette size) to explain how populations ...

Asexual, or vegetative, reproduction in plants is controlled by environmental conditions, but the molecular signaling pathways that control this process are poorly understood. Recent research suggests ...

Plant reproduction is highly complex and variable across the kingdom. The emergence of sexual reproduction has contributed to increase plant genetic diversity and enabled the colonisation of new ...

Conservation scientists for the San Diego Zoo Wildlife Alliance made the surprising discovery while genotyping genetic material from two deceased California condors Two California are currently the ...

In the course of evolution, animals have repeatedly shifted from sexual to asexual reproduction. The first evidence of the consequences of parthenogenesis – a type of asexual reproduction – on genome ...

Reproduction in the animal kingdom has historically been sexual. Cloning the sheep Dolly in 1997 moved us closer to the possibility of duplicating other animals or humans asexually, but the practice ...
