Causes of Chromosome Breaks,he same size from individuals whose average age was 55.8 years, abnormalities were found in 2.4 percent of cells (Kuhn and Therman, 1979b). Interestingly, the sensitivity of lymphocytes to alkylating agents increases significantly from newborns to young adults (mean age 23) to old people (mean age 70) (Bochkov and Kuleshov, 1972).

Structure of the Eukaryotic Chromosome and the Karyotype,ral condition is increased by a prefixation treatment with various drugs, for example, colchicine. During mitotic metaphase, the condensed chromosomes appear in identifiable shapes characteristic of the karyotype of the species being studied.

Longitudinal Differentiation of Eukaryotic Chromosomes,omosomes that are more condensed than the rest have also been called ., whereas those that are less condensed are . The same chromosome may at some stages be positively, at others negatively, heteropycnotic. The X chromosome in the spermatocytes of grasshoppers is an example of this.

The Main Features of Meiosis, in the mosses. In those organisms in which the haploid phase dominates, the diploid generation may be represented by only one cell, the zygote. Under those circumstances, meiosis takes place immediately after fertilization.

Confound

Reciprocal Translocations,ides a mechanism to isolate two populations. The spontaneous rate of interchanges is estimated to lie between 10. and 10. per gamete per generation in such different organisms as ., grasshopper, mouse, and man (Lande, 1979).
