Cytogenetics of Holokinetic Chromosomes and Inverted Meiosis: Keys to the Evolutionary Success of Mites, with Generalizations on Eukaryotes

1994
The evolution of sexual reproduction has seen a recent and major resurgence as a topic of interest. Many authors (e.g. Ghiselin 1974, Williams 1975, Maynard Smith 1978, Bell 1982, Shields 1982, Bull 1983, Michod and Levin 1988) have refined the now-familiar arguments that generally cast sexual reproduction as the alternative to the asexual production ...

Experimental demonstration of holokinetic chromosomes, and of differential “radiosensitivity” during oogenesis, in the grass mite, Siteroptes graminum (Reuter)

Journal of Experimental Zoology, 1972
AbstractEarly cleavage stages, mature eggs and developing oocytes of the grass mite Siteroptes graminum (Reuter), formerly Pediculopsis graminum (Reuter), (2n = 6; males haploid), were irradiated to: (a) test the hypothesis that the chromosomes are not monokinetic, (b) determine whether the chromosomes respond differently to irradiation during ...

Fate of fragments and properties of translocations of holokinetic chromosomes after X-irradiation of mature sperm of Tetranychus urticae koch (acari, tetranychidae)

Mutation Research/Fundamental and Molecular Mechanisms of Mutagenesis, 1979
After irradiation of mature sperm in males of Tetranychus urticae, early cleavage stages were scored for chromosome fragments. As expected from the presumed holokinetic nature of the chromosomes, the majority (94.29%) of the fragments pass mitosis without difficulty.
