摘要: It is shown that mutations mei8 (irregular condensation and fragmentation of meiotic chromosomes),sy1(asynapsis), sy10 (heterologous synapsis) rye Secale cereale L. are nonallelic. In double mutants sy1 both expressed simultaneously independently each other. A study joint inheritance revealed their interaction by means recessive epistasis: the sy1sy10 has phenotype. This gene controls an earlier stage synapsis in prophase than gene. Mutation mei8is inherited but it linked to (recombination frequency 26.8 ± 3.58%).
