Etymology
From hyper- + haploidy.
noun
- The state of having more than the haploid complement of chromosomes.“The frequency of sperm-derived hyperhaploidy did not differ significantly between the in vivo (3.4%) and in vitro (5.9%) populations, but did between unaged (2.5%) and aged (6.8%) sperm (chi c2 = 5.74, P less than 0.01). All hyperhaploid zygotes had a complement of n + 1 chromosomes, except the 14-d in vitro group, where complements of n + 2 and n + 3 chromosomes were seen.”
