“…On the basis of the data, a decision can be made about the dose levels to be used in the induction of useful translocations, for research on transmission of semisterility (Bauer, 1967;LaChance, 1970) and the application of semisterility in control of pest populations (North and Holt, 1968;Knipling, 1970).…”

“…In an earlier study (Lachance et al, 1970), we observed that adult male Oncopeltus irradiated with 9 krad produced 27 male and 14 female F, progeny, a sample too small for significant statistical analysis. The present results indicate there is no significant shift in sex ratio in the progeny of irradiated male or female Oncopeltus.…”

Adult Oncopelfus fasciatus were irradiated as 7-to 8-day-old males, and as 3-to 4-or 10-to 12-day-old females with doses of 8 and 20 krad of gamma irradiation and 200 R of X-rays, respectively. Treated bugs were outcrossed to untreated bugs, and F, progeny derived from irradiated sperm and from prophase and metaphase oocytes were studied. All treated bugs were less fertile than the controls, but none of the treatments produced full sterility. Among the F, generation from the three types of crosses, there was no significant deviation from a 50:50 sex ratio.When F, males were outcrossed to untreated females, only the males derived from irradiated sperm were semisterile; F, males derived from the treated oocytes were as fertile as the controls. The semisterility of the Fl males was correlated with chromosome translocations and fragments in the spermatocytes. The virtual absence of these aberrations in the testes of Fl males derived from irradiated oocytes suggests that these aberrations are not induced in oocytes, are repaired, or are not included in the maternal pronucleus after irradiation of meiotic oocytes.

“…One could, of course, argue that the first division is suppressed and that the division observed is the second. In the leafhopper Oncopeltus, chain quadrivalents tend to assume an axial linear orientation (John & Claridge, 1974;La Chance et al, 1970) perpendicular to the equator, quite opposite to the amphitelic orientation. This would suggest that in this genus' the chromosome end is favoured for leading M-I orientation and A-I movement.…”

The kinetic activity of chromosomes is either distributed evenly along the length of the chromosome or localized in a single centromere. Within the group of organisms with evenly distributed (holokinetic) activity great variation occurs, which has its consequences for chromatid segregation. Three major types, with some overlap, can be distinguished. They form a gradient of increasing specialization. Arguments are presented for the hypothesis that the monokinetic chromosomes are nothing but the end point in the same gradient and do not form a fundamentally different category. These arguments include: concentration of kinetic activity at meiosis in some types of holokinetic chromosomes, and 'atavistic' traits in monokinetic chromosomes pointing to a holokinetic origin. Possible reasons for the wide distribution of monokinetic chromosomes in the more evolved taxa are given.
