A team led by biologists at The University of Texas at Arlington has published a study supporting the theory that species that reproduce asexually have more harmful genetic mutations than those ...

Hermaphroditic plant species reproduce with variable rates of selfing, ranging from strict selfing to strict outcrossing (Barrett, 2002). Self-incompatibility (SI) is a reproductive system that ...

Not all creatures need to breed to produce offspring. Animals like zebra sharks and killifish are redefining what scientists thought they knew about asexual reproduction. Gabe Allen is a ...

(Santa Barbara, Calif.) Why are most organisms sexual? The question of why most species reproduce sexually and others reproduce asexually has stymied biologists for years (particularly since asexual ...

For most living things, sexual reproduction has proven the best overall strategy to perpetuate a species in the rough-and-tumble, unpredictable fray of natural selection. With two partners combining ...

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 ...

Scientists have nailed the biomechanics of a centuries-long puzzle on how freshwater flatworms known as planarians reproduce. The asexual freshwater worms, notoriously difficult to study, tear ...

Neotyphodium endophytes are asexual, seedborne fungal symbionts that are thought to interact mutualistically with their grass hosts. Benefits include increased growth, reproduction, and resistance to ...

A scientist has moved a step closer to turning sexually-reproducing plants into asexual reproducers, a finding that could have profound implications for agriculture. Farmers throughout the world spend ...
