Usage: biology; genetics

1. Of or relating to an organism with four sets of chromosomes from a single species.
Usage: biology; genetics

Examples

• Wheat is an autotetraploid organism with four complete sets of chromosomes.
• The autotetraploid condition arose through spontaneous chromosome doubling in the plant.
• Scientists studied the autotetraploid variety to understand polyploidy in crops.
• This autotetraploid species exhibits increased genetic variation compared to its diploid ancestor.
• The breeding program focused on developing autotetraploid lines with improved yield.
• Autotetraploid organisms often show greater vigor and adaptability than diploids.
