Usage: technical; biology

Examples

• Wheat is an allopolyploid that arose from hybridization between different ancestral species.
• The allopolyploid nature of the plant made it sterile until chromosome doubling occurred.
• Scientists study allopolyploid crops to understand how new species can form through polyploidy.
• This allopolyploid organism contains chromosome sets from both parent species.
• The formation of allopolyploids is an important mechanism of speciation in plants.
