noun

Specialized

: amfidiploidia

Amphidiploidy occurs when an organism inherits two complete sets of chromosomes from each of two different species, resulting in a fertile hybrid.

Examples

Amphidiploidy often results from hybridization between two distinct species, followed by chromosome doubling.
The study focused on the effects of amphidiploidy in wheat breeding programs.
Scientists created an artificial amphidiploidy to increase the plant's genetic diversity.
The plant exhibits amphidiploidy as a result of hybridization.
Researchers are studying amphidiploidy in various plant species.
In plant science, amphidiploidy is often used to describe the genetic makeup of new species created through hybridization.
The occurrence of amphidiploidy has significant implications for biodiversity in agricultural crops.

Morphology

amphidiploidy = amphidiploid (semi-transparent) = amphi + diploid + y

The formation of a noun of state from the adjective 'amphidiploid' by adding '-y' is a regular, transparent morphological process.

Etymology

The word amphidiploidy breaks into amphi- 'both', diplo- 'double', and -ploidy 'set', as in diploid. So it means 'double sets from both', which helps you remember that an amphidiploid has two full chromosome sets, one from each of two species.
