摘要: Inheritance of two spontaneous meiosis-specific mutations with similar cytologic phenotype was studied. Both were independently obtained from rye populations (Vyatka variety and weedy rye). are recessive, allelic, monogenically inherited; the corresponding gene is designated mei8. The mutant alleles cause abnormal meiotic chromosome structure expressed as irregular compaction along length, chromatin stickiness at all stages meiosis, fragmentation in anaphase I.
