Genetic chromosomes and genome mutations are taken into consideration. For a comparative study of mutagenesis types, data of separate families of seed plants bearing various vital forms of different evolutionary age were used. It was indicated that, in most ancient gymnosperms, the primitive mechanism of genetic mutation has been prevailing. In the process of evolution, chromosome and genome mutagenesis types were added, which enables the creation of new genes without functional disturbances of the ancestral system. Connections between various vital forms and mutagenese types are considered. [ABSTRACT FROM AUTHOR] |
