comparative study of mitotic and meiotic chromosomes of Aucuba japonica Thunb

The somatic metaphase chromosomes of ten strains of Aucuba japonica, a tetraploid species with chromosome rearrangements, have been compared. Only slight differences in the length of the chromosomes and in the location of the centromeres have been observed between the strains studied, but some devia...

Description
Summary:The somatic metaphase chromosomes of ten strains of Aucuba japonica, a tetraploid species with chromosome rearrangements, have been compared. Only slight differences in the length of the chromosomes and in the location of the centromeres have been observed between the strains studied, but some deviations within certain chromosome types have been recorded. Reinvestigation of meiosis has confirmed most of the earlier observations. The number of translocations and their location and size are discussed.
