1. Organisms or cells that contain four sets of chromosomes derived from two different species, typically formed through hybridization and chromosome doubling.
Usage: technical; biology; genetics; plural form of allotetraploid

Examples

• Allotetraploids are commonly found in plant species that have undergone natural hybridization.
• The wheat plant is an example of an allotetraploid with genetic material from multiple ancestral species.
• Scientists study allotetraploids to understand how new species evolve through polyploidy.
• These allotetraploids exhibit increased genetic diversity compared to their diploid parents.
• Breeders have created allotetraploids in the laboratory to develop crops with desirable traits.
