Chromosome distribution in neuroblast metaphase cells of Lucusta migratoria L.

Chromosome distribution has been investigated at metaphase and C-metaphase in neuroblast cells of Locusta migratoria embryos. There is no evidence for generalised somatic association of homologues or nucleolus organising chromosomes at either stage. Homologous chromosomes 9 are found closer together than expected in C-metaphase but this seems to be due to their tendency to lie in the centre of the C-metaphase squash.
