    abstract = {The objective of the given research is to study changes in 
  crossing over frequency and state of main components of fitness at linear flies 
  <I>D. Melanogaster</I> in dependence on age and experimentally created modifications 
  in the genotype. Research techniques are traditional and well applied in genetics 
  methods of revealing main components of fitness <I>D. melanogaster</I> in particular 
  fertility, survival in extreme conditions (high temperature exposure and starvation), 
  life expectancy etc., are used. Beside before mentioned physiological components 
  of fitness genetic (defining crossing over frequency) and genetic biochemical 
  (defining functional state of gene-enzymatic system Adh) characteristics of 
  fitness are also applied. Crossing over frequency, activity and thermal resistance 
  have been defined with the help of common methods. Being guided and published 
  in special literature data we have used these characteristics to evaluate viability 
  and general fitness of <I>D. melanogaster</I>. Reliability of the obtained data 
  has been evaluated according to student criterion (p&lt;0.05). The analysis 
  result prove that fertility differs in mutants according to the age except the 
  wild type which has more ability in fertility and unchangeable with age and 
  all the mutants lines of <I>Drosophila melanogaster</I> (b, cn, cn and vg) have 
  more fertility than the others. The data of showed that the mutant liens of 
  <I>Drosophila maelanogaster</I> (b, cn, cn and vg) have more fertility than 
  the other mutants. This fact should be taken into consideration while creating 
  new genotypes through outbreeding, genetic engineering and while developing 
  genetic theories of maturation and aging.}
