noun

The state of being dihaploid.

Supplement

Dihaploidy results from the haploidisation of polyploids. The process of producing such a condition in plants is important for selective breeding, especially of tetraploid crop plants like potatoes.

Word origin: dihaploid - coined by Bender in 1963 to combine in one word the number of genome copies (diploid) and their origin (haploid).
Related forms: dihaploid (noun, adjective), dihaploidic (adjective).
