Seagrass found to produce new genetic individuals rather than clone itself, offering hope for 'underwater meadows'

Genetic Diversity Marine Conservation Botanical Research

Researchers have discovered that the seagrass species Amphibolis antarctica reproduces sexually, producing genetically diverse seedlings rather than clones. This finding suggests new strategies for marine conservation and the restoration of seagrass meadows to increase their resilience to environmental stressors.

“New research shows that seagrass reproduces sexually, delivering new genetically diverse seedlings that disperse on ocean currents to form new meadows.”
VERIFIED
The Smithsonian Ocean source confirms that seagrasses produce flowers and seeds, which is the mechanism for sexual reproduction and genetic diversity. While the specific 'new research' aspect isn't detailed, the biological fact is verified.
