hyperhaploidy

Definitions

The state of having more than the haploid complement of chromosomes.

uncountable, usually

Examples

“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.”

“Additional work⟳ is required to confirm⟳ the real frequency of hyperhaploidy in the heterogeneous population of germ cells retrieved at testicular level.”
