Diagnosis: Identifying Cytogenetic Causes of Variants of the Karyotype and the Generative Cycle,n the diagnosis of variants of the karyotype and of the reproductive cycle deals with methods for collecting specific cytogenetic information about specific material, by making use of their typical karyological and meiotic characteristics. The analysis should include any additional, relevant informa

Estimating, Recording and Manipulating Recombination,ion of alleles present in the genomes of the parental gametes from which the individual concerned has been formed. The subject is discussed in most textbooks on general genetics. The . of recombination is based on the expression of the relevant alleles in the phenotype (in the broadest sense) of the

Manipulation of Genome Composition. B. Gene Dose: Duplication, Polyploidy and Gametic Chromosome Nu A decrease in gene dose involving chromosome segments (deficiencies) is usually intended to remove specific genes and has been mentioned in Sections 5.1.2, 8.3.2.2.1 and 10.1. Removal of entire chromosomes results in monosomy or nullisomy which have their special applications in research and chromo

Manipulation of the Genetic System,ugh generative (or, exceptionally, vegetative) reproduction. In the case of apospory, with vegetative reproduction as an extreme form, there is no generative reproduction in the strict sense. However, in the cases where true embryos in seeds are formed, it is convenient to consider apospory as a spe

Manipulation of Genome Composition: A. Gene Transfer,ccasionally even a different but closely related species (the secondary gene pool) is used. The combination of selected alleles of specific genes or on more complex combinations of less clearly defined gene complexes. This is the simples form of genetic manipulation.

Manipulation of the Genetic System,erative reproduction in the strict sense. However, in the cases where true embryos in seeds are formed, it is convenient to consider apospory as a special form of generative reproduction with a special genetic system: the genetic composition is fundamentally identical to that of the parent, except for incidental mutations and somatic segregation.
