1992, MC Sapp, PA Martin-DeLeon, “Sperm age, sex ratio, and hyperhaploidy frequency in mice”, in Cytogenetics and Cell Genetics, volume 61, number 1, →DOI, →PMID, pages 61–66: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.
