Chromosome Deletionsnslocations. These four classes can be grouped as follows: In deletions and inversions the chromosome breaks are confined to one pair of chromosomes only, whereas in duplications and translocations more than one chromosome pair can be involved in chromosome breakage.

Structure and function are necessarily closely related. Many structural features are the basis for the function of chromosomes. The genetic units of the chromosomes are the genes. Genes seem t

These investigators found that the most important result of fertilization was the fusion of gametes of maternal and paternal origin. Since the nuclei of a particular species maintain their constant chromosome number (2n) from generation to generation, the

In the last chapter we stated that the processes of genetic recombination in meiosis are: (1) crossing over of chromatid segments during prophase I and (2) random distribution of maternal and paternal chromosome segments during the f

Because . differ from the majority of chromosomes in humans, animals and plants, they are considered unusual. But apparently, in some instances, such chromosomes fulfill a need that cann
