Eggs from jnj^Δ35/jnj^Δ35 mothers exhibit a significant reduction in hatching rate, as compared to wild type, and a subset of these embryos arrest at embryonic stage 2, but both of these phenotypes are suppressible when reared at 18[o]C instead of 25[o]C. Embryos also exhibit developmental delay and nuclear abnormalities that are not suppressible by rearing at 18[o]C, including nuclear degeneration and erroneous nuclear divisions; at stages 4-5 exhibit a "nuclear fallout" phenotype wherein faulty nuclei are actively removed into the yolk; after cleavage cycles these embryos exhibit frequent anaphase-bridge formation and gaps in the embryonic cortex; but no abnormalities in eggshell patterning are observed.

jnj^Δ35/jnj^Δ35 mutant females exhibit an increase in X chromosome, but not autosome, non-disjunction during meiosis, and this phenotype is suppressible by rearing flies at 18[o]C instead of 25[o]C; no difference in crossover rate is seen in these mutants, as compared to controls. Germaria in jnj^Δ35/jnj^Δ35 mutant females exhibit similar levels of DNA double stranded breaks compared to wild type, but these are insufficiently repaired in mutants, and this phenotype is suppressed when rearing flies at 18[o]C instead of 25[o]C. Ovaries of jnj^Δ35/jnj^Δ35 mutant females exhibit increased pachytene arrest and delayed karyosome dynamics, as compared to wild type.

SMC6^Δ35 has abnormal meiotic cell cycle | female | temperature conditional phenotype, suppressible by mei-W68^2-0949/mei-W68^2-0949
