Examples

• Amphidiploids are commonly produced in plant breeding programs to create fertile hybrids.
• The wheat species is an example of a naturally occurring amphidiploid.
• Scientists created amphidiploids by doubling the chromosome number in sterile hybrid plants.
• Amphidiploids often exhibit greater genetic stability than their diploid hybrid parents.
• Many crop plants, including cotton and tobacco, are amphidiploids.
