From: Preferential segregation of metacentric chromosomes in simple Robertsonian heterozygotes of Sorex araneus

Figure 3

(a) Hyperploid MII spread of the individual heterozygous for jl chromosome arm combination; the type B cell with 14 chromosomes and one acrocentric extra (arrows indicate six acrocentric chromosomes). (b) The only case of diakinesis spread with probable ring configuration of nr trivalent. It is not clear which one, out of the two elements indicated by arrows, really represents nr arm combination. (c) Arrow indicates chain configuration of nr trivalent. MII, metaphase II.
