英文摘要: Summary(#br)In Pisum sativum tertiary trisomics and trisomic interchange heterozygotes have been derived from Hammarlund’s K -line interchange heterozygote, which has a meiotic association of four chromosomes. The origin of the trisomics is shown to be in numerical non-disjunction of the association of four in one only of the four possible ways.(#br)Eleven different types of trisomic may occur when the two original types are selfed. Progenies of selfed trisomics are described, including one new (primary) trisomic.(#br)The degree of sterility of the trisomics is discussed.(#br)An analysis is made of single-gene ratios expected among trisomics in the progeny of interchange heterozygotes. These ratios provide a means of locating genes in the interchanged chromosomes.(#br)Other trisomics...
